A Costco Gold Star membership costs $65/year. Most members justify it with bulk groceries and gas. They walk in, load a cart with paper towels and rotisserie chicken, fill up the tank, and leave. That's Costco to 90% of its 135 million members. What most members don't realize: the $65 membership includes access to 11 services beyond the warehouse floor that save $2,000-$4,000/year services most members have never used, never visited, and in some cases never heard of. A Costco employee of 8 years told his neighbor: "You come in every Saturday. You buy groceries. You get gas. You leave. You've used 3 of the 14 things your membership gives you access to. You've never used the pharmacy which sells prescriptions 30-80% below CVS and doesn't even require a membership. You've never used the optical center where glasses cost 40-60% less than LensCrafters. You've never used the tire center where the purchase price includes free installation, lifetime rotation, balancing, flat repair, and a road hazard warranty. You've never checked Costco Travel which books vacation packages cheaper than Expedia with member-only extras. You've never used the auto program which gives you a pre-negotiated car price with zero haggling. You've never used the hearing center where hearing aids cost $999-$1,699 versus $4,000-$7,000 at private audiologists. And you've never read the price tags which have a coded language telling you which items are clearance, which are manager specials, and which are about to disappear forever." His neighbor said: "I've been a member for 6 years." "And you've used 20% of your membership for 6 years while the other 80% sat in departments you walked past every Saturday." He showed her 11 things. Her annual Costco savings went from $800 to $3,200 same membership, same warehouse, same weekly trip. Here are the 11 things 🧵

First why Costco hides its best services behind departments most members never visit. Costco's business model is unique in retail: they make almost zero profit on the products they sell. Costco's average markup on goods is 11-14% compared to 25-50% at traditional retailers. Their profit comes almost entirely from membership fees $4.8 billion in membership revenue in 2025. This means Costco has one financial incentive: keep you as a member. The way they keep you is by making the membership so valuable across so many categories that canceling feels like losing money. But here's the paradox: Costco doesn't aggressively market most of its services. The pharmacy isn't advertised on TV. The travel portal isn't promoted on the homepage. The hearing center doesn't have billboards. The auto program doesn't run radio ads. Why? Because Costco's growth is driven by word of mouth and renewal rates not by advertising spend. They invest in value instead of marketing. The services exist. The prices are extraordinary. The promotion is almost nonexistent. The result: 135 million members most of whom use 3-4 services (warehouse, gas, food court, maybe pharmacy) and have never explored the other 10. Not because the services aren't valuable. Because nobody told them to walk past the bulk paper towels and look at what's behind them. Every service in this thread is available right now at your Costco, with your membership, at prices that undercut the specialists you're currently paying full price.

1. The price tag codes the secret language on every sign in the warehouse. Every Costco price tag contains coded information about the deal you're looking at and 90% of members have never learned to read it. The codes: Price ending in .99 or .89: standard Costco pricing. This is the regular price already lower than most retailers, but not a special deal. Price ending in .97: manager markdown. This item has been marked down at the store level clearance pricing. It won't be restocked. Once the shelf is empty, it's gone. These markdowns are never advertised. They sit on the shelf next to full-price items. The only way to spot them is to read the tag. Typical discount: 30-50% off the original price. Price ending in .00 or .88: manager's special. Deep markdown often due to excess inventory, damaged packaging, or end-of-season clearance. These are the deepest discounts in the building. Price ending in .49 or .79: manufacturer markdown. The manufacturer not Costco has reduced the price for an exclusive Costco promotion. These are factory-level discounts that don't appear at other retailers. Asterisk (*) in the top-right corner: discontinued. This item will not be reordered. Whatever is on the shelf is the last of it nationally. If you love it, buy it now. It's not coming back. She'd been walking past .97 clearance items for 6 years — picking up the .99 version of the same product on the next shelf. The .97 was 30-40% cheaper. Same product. Different tag. She'd never looked at the last two digits. "The price tags are a conversation between Costco and the members who know how to listen. .97 says 'last chance, deep discount.' .00 says 'we need this gone.' Asterisk says 'forever.' Most members hear nothing — because they look at the price, not the code."

2. Kirkland Signature — the name brands hiding behind a private label. Most people assume Kirkland Signature — Costco's private-label brand — means generic. Lower quality. Budget ingredients. Made by some unknown manufacturer in a warehouse somewhere. The reality: many Kirkland products are manufactured by the name brands themselves — on the same production lines, with the same ingredients or materials — under the Kirkland label at 30-50% less. The confirmed and widely reported connections: Kirkland batteries: manufactured by Duracell. Same factory. Same chemistry. Different label. 40% less. Kirkland coffee: multiple varieties roasted by Starbucks. The Kirkland Signature House Blend and Espresso Blend are roasted at Starbucks facilities. A 2.5-pound bag of Kirkland: roughly $14. The equivalent in Starbucks bags: $25-$30. Kirkland diapers: made by Kimberly-Clark — the parent company of Huggies. Parents who've used both report virtually identical performance. Kirkland: roughly $0.14/diaper. Huggies: $0.25-$0.35/diaper. Kirkland olive oil: sourced from premium Italian producers. Has won blind taste tests against $20+ bottles from specialty retailers. Kirkland price: roughly $12-$15 for a liter. Kirkland golf balls: manufactured in factories that produce premium balls. Performance comparable to Titleist Pro V1 in independent tests. Kirkland: roughly $1/ball. Titleist Pro V1: $4/ball. Kirkland vodka: widely reported (though never officially confirmed by either company) to be produced at facilities connected to Grey Goose production. Kirkland: roughly $20 for 1.75L. Grey Goose: $30-$40 for 750mL. The math: switching from name brands to Kirkland on 10 common household items saves the average family $40-$60/month — $500-$720/year. Same manufacturers. Same production quality. Different label. Different price. "Kirkland isn't generic. It's name-brand products without the name-brand marketing budget. The $15 you save per item isn't a quality sacrifice — it's the marketing cost you stopped paying."

3. The pharmacy — 30-80% cheaper than CVS, and you don't even need a membership. By federal law, Costco's pharmacy must be accessible to non-members. You don't need a Costco card. You walk in. You fill the prescription. You walk out. The prices are extraordinary: Common generic prescriptions that cost $40-$80 at CVS or Walgreens frequently cost $5-$15 at Costco. Many 90-day supplies of common generics are available for $9.99 at Costco — compared to $30-$60 for a 30-day supply at chain pharmacies. Why Costco's pharmacy is cheaper: Costco charges lower dispensing fees than CVS, Walgreens, and Rite Aid. They negotiate directly with manufacturers for lower drug costs. They don't mark up prescriptions the way traditional pharmacies do — because the pharmacy is a membership benefit, not a profit center. The pro tip: even with insurance, check Costco's cash price before using your insurance copay. In many cases, Costco's cash price — the price you pay without running insurance — is lower than your insurance copay. A $25 insurance copay on a drug that Costco sells for $9.99 means you'd save $15 by not using insurance and paying Costco's cash price instead. His neighbor was paying $74/month for a prescription at CVS — with insurance. She filled the same prescription at Costco pharmacy. Cash price: $18. She saved $56/month — $672/year — on one medication. Without using her insurance. Without using her Costco membership. "Your pharmacy is a profit center for CVS. Costco's pharmacy is a membership benefit — priced to attract members, not to generate prescription margins. The same pill, from the same manufacturer, costs 30-80% less. And you don't need a membership to walk in."

4. The optical center — glasses at 40-60% less than LensCrafters. Costco's optical department sells prescription glasses, contacts, and provides eye exams — at prices that consistently undercut LensCrafters, Visionworks, and private optometrists by 40-60%. What Costco optical offers: Eye exams: performed by licensed independent optometrists who lease space inside the Costco warehouse. Exam prices vary by location but typically run $70-$90 — compared to $100-$150 at private optometrists and $75-$125 at LensCrafters. Prescription glasses: frames + lenses starting at roughly $100-$200 for quality frames with standard lenses. The same quality at LensCrafters: $250-$500+. Premium lenses (progressive, anti-reflective, blue-light filtering): significantly less than optical chains. Contact lenses: bulk pricing on major brands — Acuvue, Air Optix, Biofinity — at prices that match or beat online retailers like 1-800-Contacts. She was buying glasses at LensCrafters — $380 for frames + progressive lenses. She got the same prescription filled at Costco optical: $165 for comparable frames and progressive lenses. $215 saved on one pair of glasses. She buys new glasses every 2 years. Costco savings per pair: $200+. Over 10 years: $1,000+ — on the same quality frames and lenses, filled by a licensed optometrist, at the store she was already visiting for groceries. "LensCrafters charges a premium for the mall location, the brand name, and the marketing. Costco optical charges for the glasses. The prescription is the same. The lenses are the same. The exam is comparable. The price is half."

5. The tire center — where the purchase price includes everything other shops charge extra for. Costco's tire center sells major brands — Michelin, Bridgestone, BFGoodrich, Goodyear — at competitive prices. But the price isn't what makes the tire center exceptional. The included services are. What's included with every tire purchase at Costco: Free installation. Free lifetime balancing (for the life of the tires). Free lifetime rotation (for the life of the tires). Free flat repair (for the life of the tires). 5-year road hazard warranty (covers damage from potholes, nails, debris — repair or replacement). Free nitrogen inflation (maintains tire pressure longer than regular air). At a typical tire shop — Discount Tire, Firestone, Pep Boys — you pay the tire price plus $15-$25/tire for installation, $10-$15/tire for balancing, $20-$30 per rotation visit, and $25-$50 for road hazard coverage per tire. Over the life of a set of tires: $150-$300 in services you'd pay for elsewhere — included free at Costco. The total value: Costco's tire price is typically competitive with (and sometimes lower than) Discount Tire. The included services add $150-$300 in value. Combined: Costco's tire center delivers the best total tire ownership cost available to consumers. He bought 4 Michelin tires at Costco: $780 installed — with lifetime rotation, balancing, flat repair, and a 5-year road hazard warranty included. His quote at Discount Tire for the same Michelins: $820 for tires + $60 installation + $40 balancing + $80 road hazard = $1,000. Same tires. $220 difference. "The tire price at Costco isn't always the cheapest sticker. The tire ownership cost — including everything you'd pay for separately at every other shop — is almost always the cheapest total."

6. The gas station — 20-40¢/gallon cheaper, adding up to $150-$300/year. Costco gas stations consistently price fuel 20-40¢ per gallon below nearby stations — often the cheapest gas in any given metro area. The math: Average savings: $0.30/gallon. Average fill-up: 15 gallons. Savings per fill-up: $4.50. Fill up weekly: $4.50 × 52 = $234/year. For a two-car household filling up weekly: $468/year in gas savings — which alone covers the $65 Gold Star membership fee 7 times over. The Costco Anywhere Visa by Citi amplifier: The Costco credit card earns 5% cash back on gas purchased at Costco (and 4% on gas elsewhere), up to $7,000 in gas spending per year. On $3,500/year in Costco gas purchases: $175 cash back — on top of the per-gallon savings. Combined: $234/year in per-gallon savings + $175 in credit card cash back = $409/year from gas alone. More than 6x the membership fee. She was filling up at the Shell station 0.8 miles from her house — $3.89/gallon. The Costco gas station 1.2 miles from her house: $3.49/gallon. Same commute. Same direction. $0.40/gallon difference. $312/year in savings — from driving 0.4 miles further. "Costco gas pays for the entire membership — and then some — before you walk into the warehouse. Most members know Costco gas is cheap. Most members don't realize exactly how much the savings add up to over a year."

7. Costco Travel — vacation packages that beat Expedia with member-only extras. Costco Travel is the most underused member benefit in the entire Costco ecosystem — and the one that delivers the largest per-transaction savings. What Costco Travel offers: Vacation packages: bundled flights + hotels + rental cars — often at prices 10-25% below Expedia, Booking.com, and Kayak for comparable itineraries. Member-only extras: many Costco Travel packages include perks the OTAs don't — resort credits ($100-$300 in spending money at the resort), room upgrades, free breakfast, spa credits, or excursion vouchers — included in the package price. Cruises: Costco negotiates group rates with major cruise lines — often including onboard credits ($50-$200) that other booking channels don't offer. Rental cars: member-exclusive pricing on Avis, Budget, and Enterprise — often 10-20% below what you'd find on the rental car company's own website. Theme parks: discounted tickets to Disneyland, Disney World, Universal Studios, and other parks — with bundled hotel packages. Executive members earn 2% back on Costco Travel purchases — applied to their annual reward. A $5,000 Hawaii package earns $100 in Executive Reward. She booked a family vacation through Expedia: flights + 5-night resort in Cancun = $4,200. Her neighbor booked the same resort, same dates, through Costco Travel: $3,580 — with a $200 resort credit included. $620 less + $200 in resort spending money. $820 in total value difference — on one vacation. "Costco Travel doesn't look flashy. The website is basic. There's no app. The interface feels like 2010. And the prices — consistently — beat Expedia, Booking, and the cruise lines' own websites. Most members book travel without checking Costco first. The members who check Costco first save $300-$800 per trip."

8. The auto buying program — buy a car without negotiating. The Costco Auto Program connects members with pre-negotiated pricing at participating dealerships — eliminating the most hated part of car buying: haggling. How it works: Go to costcoauto.com. Select the make, model, and trim you want. The system connects you with a participating dealer in your area. The dealer offers you a pre-arranged Costco member price — a fixed, non-negotiable price that's typically $500-$2,000+ below the sticker price and competitive with what aggressive negotiators achieve after hours of back-and-forth. You walk in. You test drive. You accept the pre-arranged price. You drive away. No negotiation. No "let me talk to my manager." No pressure tactics. No 4-hour dealership experience. The program works for new and pre-owned vehicles. The pricing is transparent — you see the member price before you visit the dealer. He spent 4 hours at a Toyota dealership negotiating the price of a Camry. He haggled. They countered. He walked out. They called back. He came back. They settled $1,200 below sticker after an exhausting afternoon. His neighbor used the Costco Auto Program for the same Camry, same dealer: a pre-arranged price $1,400 below sticker — no negotiation, no pressure, 45 minutes at the dealership. "Car dealers make money on the negotiation. You don't. The Costco Auto Program removes the negotiation — and gives you a price that beats what most people achieve after hours of haggling. The price is pre-set. You accept or you don't. No games."

9. The hearing center — hearing aids at $999-$1,699 versus $4,000-$7,000. Costco operates hearing centers at most full-service warehouse locations — staffed by licensed audiologists and hearing aid dispensers who provide comprehensive hearing assessments and premium hearing aids at prices that are dramatically below private audiology practices. What Costco hearing center offers: Free hearing tests: a professional hearing assessment in a private sound booth — at no cost to members. No appointment fee. No consultation charge. Premium hearing aids: from brands including Philips, Jabra, and Rexton — at $999-$1,699 per pair. The same brands and comparable technology at private audiology practices: $4,000-$7,000 per pair. Free follow-up care: adjustments, cleanings, and checkups — included for the life of the hearing aids. 180-day return policy: one of the most generous in the hearing aid industry. If the hearing aids don't work for you, return them within 6 months for a full refund. Loss and damage coverage: included with select models. He was quoted $5,200 for a pair of Philips hearing aids at a private audiologist. His wife suggested checking Costco. Same brand. Comparable technology. $1,499 at Costco. He saved $3,700 — on the same hearing aids, with free follow-up care and a 180-day return policy the private audiologist didn't offer. "Hearing aids are one of the most overpriced medical devices in America. The Costco hearing center cuts the price by 60-75% — with free testing, free follow-up, and a 180-day return policy. Most members don't know the hearing center exists — because it's in a corner of the warehouse they've never visited."

10. The return policy — the most generous in retail, and the one most members underuse. Costco's return policy is legendary — and most members still don't understand how generous it actually is. The standard policy: Costco accepts returns on almost any product, at any time, with no time limit — with a few exceptions. No receipt required (Costco tracks purchases by membership card). No questions asked. Full refund. The exceptions: Electronics (TVs, computers, tablets, phones): 90-day return window. Diamonds over 1 carat: requires documentation. Cigarettes and alcohol: limited by law in some states. Everything else — food, clothing, furniture, appliances, household goods, outdoor equipment, fitness equipment — has no time limit. If you bought a mattress 2 years ago and it's sagging, return it. If a kitchen appliance breaks after 18 months, return it. If a jacket's zipper fails after a year, return it. The Costco Concierge bonus: electronics purchased at Costco come with Costco Concierge Services — free technical support and an extended manufacturer warranty (up to 2 additional years) at no extra cost. A TV bought at Costco gets a 2-year extended warranty — free — on top of the manufacturer's warranty. The same extended warranty purchased at Best Buy: $100-$300. She bought a stand mixer at Costco 14 months ago. The motor burned out. She assumed she was past the return window and started shopping for a replacement. Her neighbor said: "Return it to Costco. There's no time limit on kitchen appliances." She returned it. Full refund. No receipt (her membership card had the purchase history). She bought a replacement — at Costco — and walked out paying $0 net. "Most retailers give you 30 days. Amazon gives you 30 days. Best Buy gives you 15 days (45 for elites). Costco gives you forever — on almost everything. The return policy alone justifies the membership for anyone who's ever been stuck with a product that failed after the return window closed."

11. The Executive membership math — and why most members are on the wrong tier. Costco offers 2 membership tiers: Gold Star ($65/year) and Executive ($130/year). Most members are on Gold Star because it's cheaper. Many of them should be on Executive — because the math pays for the upgrade. What Executive adds: 2% annual reward on qualifying purchases — up to $1,250/year. The reward is issued as a check or statement credit once per year. Early warehouse access at many locations (typically 1 hour before regular opening). Additional discounts on select Costco services — insurance, travel, and more. The 2% reward applies to Costco Travel purchases as well. The math: The Executive upgrade costs $65 more per year ($130 - $65). To break even, you need the 2% reward to generate at least $65. $65 ÷ 2% = $3,250 in annual Costco spending. If you spend $3,250 or more per year at Costco — that's roughly $63/week, or $270/month — the Executive membership pays for itself entirely through the 2% reward. If you spend $6,500/year: $130 reward. You've covered the entire Executive membership fee — and the upgrade was effectively free. If you spend $10,000/year: $200 reward. You're earning $70 more than the upgrade cost — profit. The safety net: if your 2% reward at the end of the year is less than $65 (the upgrade cost), Costco will downgrade you back to Gold Star and refund the difference. There's zero risk. She was on Gold Star — spending $8,400/year at Costco. Annual savings from upgrading to Executive: $168 in 2% reward - $65 upgrade cost = $103 in profit. She'd been leaving $103/year on the table for 4 years because she assumed Gold Star was "good enough." "If you spend more than $63/week at Costco — groceries, gas, pharmacy, optical, tires, travel — Executive pays for itself and gives you money back. If you spend less, Gold Star is correct. Most members have never done the math — and Costco doesn't prompt you to calculate it."

The full system — 11 services, one $65 membership, $2,000-$4,000/year in savings. What he showed her and what each service saves: 1. Price tag codes (.97, .00, .88, asterisk): identifies clearance, manager specials, and discontinued items — $100-$300/year in savings on items you're already buying 2. Kirkland switch (10 common items): same manufacturers, 30-50% less — $500-$720/year 3. Pharmacy (no membership needed, 30-80% below CVS): $200-$800/year on prescriptions depending on medications 4. Optical center (40-60% below LensCrafters): $200-$400 saved per pair of glasses 5. Tire center (lifetime rotation, balancing, flat repair, road hazard included): $150-$300 saved per set of tires 6. Gas station (20-40¢/gallon cheaper): $150-$300/year + 5% Costco Visa cashback 7. Costco Travel (beats Expedia, includes member-only extras): $300-$800 saved per vacation 8. Auto buying program (pre-negotiated pricing, no haggling): $500-$2,000+ saved per vehicle 9. Hearing center ($999-$1,699 vs $4,000-$7,000): $3,000-$5,000 saved per pair of hearing aids 10. Return policy (no time limit on most products + free extended warranties): prevents $100-$500/year in stuck-with-broken-products losses 11. Executive membership math (2% back, risk-free upgrade): $65-$200/year in annual reward if you spend $3,250+ Membership cost: $65/year (Gold Star) or $130/year (Executive). Estimated annual savings using 6-8 of these services: $2,000-$4,000. ROI on membership: 30-60x the annual fee. Before: Costco used for bulk groceries and gas. 3 services. $800/year in savings. After: Costco used as a savings system across 11 services. $2,000-$4,000/year in savings. Same membership. Same warehouse. Same weekly trip. Different understanding of what the membership includes.

The uncomfortable truth. Costco has 135 million members worldwide. It generates $4.8 billion in membership revenue. The vast majority of those members use their membership for 3 things: bulk groceries, gas, and the food court. They fill prescriptions at CVS — paying 30-80% more for the same medications. They buy glasses at LensCrafters — paying 40-60% more for the same lenses. They buy tires at Discount Tire — paying $150-$300 more when services are included. They book vacations on Expedia — paying $300-$800 more for the same resorts. They negotiate car prices at dealerships — spending 4 hours to save less than Costco's Auto Program achieves in 4 minutes. They buy hearing aids at private audiologists — paying $3,000-$5,000 more for the same brands. They do all of this while paying $65/year for a Costco membership that includes every one of these services at dramatically lower prices — services they've never used, in departments they've never visited, on a website they've never scrolled. Costco doesn't advertise these services because Costco barely advertises at all. No TV commercials. No Super Bowl ads. No influencer partnerships. Costco's marketing budget is virtually zero — because their business model depends on value, not awareness. The value exists. The awareness doesn't. "A Costco membership costs $65/year and gives you access to the cheapest pharmacy, the cheapest optical department, the cheapest tire center, the cheapest gas, the cheapest travel portal, and the cheapest hearing aids available to consumers — plus a return policy that accepts almost anything, at any time, with no receipt. Most members use it to buy 48 rolls of toilet paper and a rotisserie chicken." 11 services. $65/year. $2,000-$4,000 in annual savings. The warehouse was always the front door. The services were always behind it. The savings were always waiting — in departments you walked past every Saturday on your way to the checkout line. Your membership was always worth more than you thought. You just never walked past the paper towels to find out how much more.
