Both warehouses will save you real money — but on different things, for different kinds of shoppers. This guide cuts past the marketing and answers the specific questions that actually change the math.
Most people come here with one specific question — “which one should I join?” — and leave with a list of caveats. Here are the honest quick answers to the questions that actually drive the decision, before the full breakdown.
1 Which membership costs less right now? Sam’s Club, but the gap just got smaller. As of May 2026, Sam’s Club raised its basic membership to $60 — just $5 less than Costco’s $65 Gold Star. Premium tier: Sam’s Plus is $120 vs. Costco Executive at $130. ▼
2 Which one has lower grocery prices? Sam’s Club on packaged goods and paper products — often noticeably so. Costco on fresh meat, produce, and anything under the Kirkland Signature label. For a single shopping trip of 30 common items, expect Sam’s to run about 15% less. ▼
3 Which is better for seniors on fixed incomes who need pharmacy and health savings? Sam’s Club on prescriptions. Costco on hearing aids. For someone managing multiple daily medications, Sam’s Club Plus gives free generics plus deeper pharmacy discounts. For hearing loss, Costco’s pricing beats most private audiologists by thousands of dollars. ▼
4 Sam’s Club or Costco for gas savings? Both typically beat local stations by 5–25 cents per gallon. Sam’s Club has about 600 locations versus Costco’s 585, so Sam’s may be closer. Costco sells Top Tier certified fuel with higher detergent levels. Sam’s Club accepts all major credit cards at the pump — Costco only accepts Visa. ▼
5 Does Sam’s Club really have a better checkout experience? Yes — by a significant margin right now. Sam’s Club’s Scan & Go app lets you scan items as you shop and walk out without a checkout line. Costco is piloting something similar at 27 locations, but has no nationwide rollout date. Long Costco checkout lines are a documented frustration even among loyal members. ▼
6 Which warehouse is more likely to be near me? Sam’s Club, especially outside of major metro areas. Sam’s has about 600 locations versus Costco’s 585, and Sam’s footprint is stronger in rural areas and smaller cities. If you live outside a large coastal metro, Sam’s Club is often the only option within easy driving range. ▼
7 What does Costco do significantly better than Sam’s Club? Return policy, fresh food quality, organic selection, travel deals, and hearing aid pricing. Costco’s return policy is nearly unlimited on most items (90 days on electronics). The Kirkland brand has cult-level loyalty for good reason. Costco Travel is genuinely exceptional for cruises and resort packages. ▼
8 Is it worth belonging to both at the same time? For a household that spends heavily at both and shops near both locations, sometimes yes — especially if you use Sam’s Club pharmacy benefits and Costco’s hearing aids and fresh food. But the combined annual cost is $125–$250, which requires honest math to justify. ▼
Membership fees at both clubs changed in 2024–2026. Here’s exactly where each tier stands and what the upgrade math looks like for different spending levels.
Access to all club locations, online shopping, and member pricing. Gas station access. Free flat tire repair regardless of where you bought the tires. In-club dining. Photo center.
Access to all warehouse locations, online shopping, and member pricing. Gas station access (Visa only). Tire center, optical, pharmacy, hearing aids. Famous food court ($1.50 hot dog still holds).
Both premium tiers earn 2% cash back and cost about $60 more than the basic tier. The upgrade pays for itself when cash back equals $60 — which happens at roughly $3,000 (Sam’s) or $3,250 (Costco) in annual warehouse spending. That works out to about $250–$275 per month at the club. A family of four doing regular grocery and household shopping can reach that fairly easily. A couple shopping occasionally for bulk staples probably can’t. The Costco Executive’s big advantage shows above that threshold: its $1,250 annual cap means a high-spending household keeps earning through $62,500 in annual purchases. Sam’s Club Plus caps out at $500, which is reached at just $25,000 in annual spending — achievable for a family or small business owner who shops heavily.
A category-by-category breakdown of where each club wins, where neither clearly leads, and which edge matters most in practice.

The grocery question is where most households make or lose the real money in their membership. Here’s what the price differences look like in practice and which private label brand delivers more value.
When researchers compared the same list of 30 grocery items at both clubs, the total ran roughly $13 less at Sam’s Club. That’s not a small gap on a typical shopping trip. Sam’s Club also runs “instant savings” events — time-limited automatic discounts applied at checkout, no app required — that can make a significant difference on specific categories. A 156-count box of Tide Pods recently ran about $6 less than the equivalent at Costco. Paper goods, canned goods, snack foods, and name-brand packaged staples tend to be where Sam’s Club holds the most consistent price edge.
Costco’s produce, meat, and bakery items consistently outscore Sam’s Club in head-to-head comparisons. The organic section at Costco is substantially deeper — if you buy organic anything regularly, this matters a lot. Kirkland Signature enjoys a level of consumer trust that Member’s Mark hasn’t matched despite its broader product count. The Kirkland olive oil, bacon, almonds, and coffee in particular have devoted followings because the quality genuinely rivals national brands at lower prices. Costco’s CFO stated in 2026 earnings calls that Kirkland items typically offer 15–20% better value than national brand equivalents — and that’s on a product line that already starts at a warehouse price.
Bulk pricing only saves money on items you’ll actually use before they expire. A gallon of olive oil from Costco is an incredible deal for a family of six — and a waste for a single person who’ll use it over three years. The honest math on any warehouse purchase: take the per-unit price, compare it to your regular grocery store or Amazon, and then ask whether you’ll realistically use the quantity before it expires. Both clubs keep far fewer SKUs than a regular grocery store — Costco stocks roughly 4,000 items versus 30,000 at a typical supermarket — so neither is a complete substitute for regular shopping.
For many seniors and fixed-income households, the health services at warehouse clubs — not the groceries — are where the most consequential savings happen. This is where the two clubs diverge most sharply.
Costco’s hearing aid centers now handle roughly 16% of all retail hearing aid sales in the United States — making them the largest non-VA provider in the country. Their Kirkland Signature hearing aids are priced between approximately $980 and $1,700 per pair, compared to $2,500 to $8,000 at traditional private audiologist offices. The technology inside the Kirkland aids is licensed from major manufacturers — the same underlying platforms used by premium national brands — and comes with free lifetime cleaning, adjustments, and follow-up care. For a senior who needs hearing aids, this one purchase can save $3,000 to $5,000 versus the private audiology route, covering years of Costco membership costs from a single transaction. Costco also offers a 180-day trial period — six full months to decide if the aids are right for you. Additionally, their lineup includes hearing aids from Jabra, Philips, Rexton, and Sennheiser at select locations, giving meaningful brand choice.
Sam’s Club hearing centers recently transitioned to a new partner arrangement in 2026, and their prescription hearing aid prices now start around $1,399 to $1,699 per pair through licensed hearing care professionals. Free hearing tests are available to the public; you need a membership to purchase hearing aids. The club’s trial window is 45 days — much shorter than Costco’s 180-day period. Sam’s Club also offers over-the-counter hearing aids starting around $200 for mild-to-moderate hearing loss. The main limitation: Sam’s Club hearing centers carry a narrower brand selection than Costco. If you have complex or severe hearing loss where brand-specific technology matters, Costco’s multi-brand lineup gives your hearing care specialist more options to match your specific audiogram.
Eye exams at both Sam’s Club and Costco optical departments typically run $50 to $100 and are open to non-members at most locations — a useful fact if you’re trying either club before committing. Prescription glasses, contacts, and sunglasses require a membership at both stores. Sam’s Club optical staff get consistently positive reviews for availability and helpfulness, and some shoppers note shorter wait times than at Costco optical — where the popularity of the service sometimes creates a wait. Pricing on frames and contacts is competitive at both clubs and generally well below retail optical chains.
Both clubs offer gasoline savings that can pay for a basic membership within a few fill-ups. Where they differ is in fuel quality, payment flexibility, and what the tire center actually does for you.
Sam’s Club’s tire and battery center offers free lifetime tire balancing and rotation, and — importantly — will repair flat tires regardless of where you bought the tires. Costco will repair flats only on tires purchased at Costco. Sam’s Club also installs batteries purchased in the club; Costco sells auto batteries but doesn’t install them. If you want a one-stop tire center that handles any car that drives in, Sam’s Club is more flexible. Costco’s tire pricing and warranty service are excellent, but the service relationship is closer-tied to having purchased tires there first.
Here’s the honest answer for six real situations — the cases where the choice isn’t complicated, and a few where it genuinely is.
