Costco vs Sam's Club 2026 honest comparison membership fees Kirkland Member's Mark gas pharmacy Scan Go food court which wins

Few questions generate more passionate disagreement among warehouse club shoppers than the Costco vs Sam's Club debate — partly because both clubs are genuinely good at different things, partly because the answer is more household-specific than most comparison guides acknowledge, and partly because the competitive landscape between these two behemoths shifted meaningfully in 2025 and 2026 in ways that most older comparison articles have not caught up with.

Deciding between Costco and Sam's Club depends on your location and shopping priorities. Both offer two membership levels for individuals, but Sam's Club's fees are lower. The stores carry many of the same services and products, but Costco typically stocks more premium items than Sam's Club. MOJO

Costco wins on selection, store quality, and member satisfaction; Sam's Club wins on value-focused shoppers and upfront savings with lower membership fees. For most households, the choice comes down to location, product preferences, and whether the membership fee gap matters to you. MOJO

This guide breaks down every meaningful dimension of the comparison — membership fees, product pricing, private label quality, gas savings, pharmacy, digital experience, food court, employee experience, and the specific shopper profile that makes each club the smarter choice. The honest answer: both clubs are genuinely good. Neither is universally superior. The right choice depends on which specific categories matter most to your household.

Round 1: Membership Fees

Sam's Club:

Basic Club membership: $50/year
Premium Plus membership: $110/year
Plus membership cash back: 2% (capped at $500/year)

Costco:

Gold Star membership: $65/year
Executive membership: $130/year
Executive cash back: 2% (capped at $1,250/year)

Both warehouse clubs use tiered memberships, and the math matters more than you'd think. Costco's edge: The $15 annual difference is small, but Costco throws in extra perks — a 2% cash back rate on Executive membership with a higher cap. Sam's Club's edge: Lower entry price and renewal bonuses help offset costs. If you only shop 2-3 times a year, Sam's Club's $50 barrier is genuinely easier to justify. Greenmo

The rewards cap difference is significant: At both stores, the higher-tier membership earns 2% cash back on purchases, but Sam's Club caps rewards at $500 while Costco's cap is $1,250. For heavy spenders — households generating $25,000 or more in annual warehouse purchases — the $1,250 Costco cap versus Sam's Club's $500 cap is a real and meaningful financial difference. For typical households, both caps are theoretical maximums that neither will approach. MOJO

Verdict: Sam's Club wins on price. The $15 lower basic membership and $20 lower premium membership make Sam's Club the more affordable entry point. The rewards cap advantage belongs to Costco for very high spenders.

Round 2: Product Pricing

In 2023, AARP investigated the prices of 30 comparable grocery items at each chain and found that, across their sample, groceries at Sam's Club are around 18.36% cheaper than those at Costco by weight. MOJO

18.36 percent cheaper at Sam's Club — that is a genuinely significant finding that most Costco loyalists resist acknowledging. The items in the AARP comparison included rotisserie chickens, wild salmon fillets, baked beans, mayo, rice, pasta, eggs, pretzels, and orange juice.

Sam's Club often comes out on top for affordability. Its membership fees are lower, the stores stock more name-brand items at lower prices and its instant savings discounts drive costs down further. MOJO

The Sam's Club instant savings mechanism: Sam's Club instant savings deals, which are offered for a limited time and applied automatically at checkout, can be compelling. For example, a 156-pack of Tide Pods was originally $29.98, but with a $6 discount it dropped to $23.98. At Costco, the same box recently cost $36.49. MOJO

The Tide Pods example is the type of specific price comparison that makes the pricing debate concrete: $23.98 at Sam's Club versus $36.49 at Costco for the same number of pods is a 35 percent differential on a specific staple product.

The counterargument — quality premium:

"The quality you get at Costco more than makes up for the small difference," Zoeller says. MOJO

Some consumers tend to view Costco's products as higher quality than their Sam's Club counterparts, but sentiment is mixed. MOJO

Verdict: Sam's Club wins on price. Costco wins on perceived quality. For budget-first shoppers, Sam's Club consistently delivers lower per-unit prices. For quality-first shoppers, Costco's product selection — particularly produce, fresh meat, and specialty food — is consistently rated higher.

Round 3: Private Label — Kirkland Signature vs Member's Mark

This is the category where the most passionate warehouse club opinions are formed — and where the quality gap between the two programs is most commercially significant.

Costco partners with major companies — including Bumble Bee (tuna), Diamond Naturals (dog food), Duracell (batteries), Huggies (diapers), Reynolds (aluminum foil), Starbucks (coffee), and others — to produce branded products for its Kirkland Signature line. MOJO

Kirkland Signature's manufacturing partnerships — with Duracell, Reynolds, Starbucks, and others — are publicly known and consistently generate the "same thing for less" response from members who value institutional quality without the brand premium. The Kirkland battery is a Duracell. The Kirkland foil is a Reynolds. The Kirkland coffee is Starbucks-roasted. These partnerships are Kirkland's commercial foundation.

Member's Mark, Sam's Club's private label store brand, can offer great value. "Sam's Club is better for business because they offer the generic versions of things for pennies on the dollar," says Joel Blackstock, a psychotherapist who has memberships at both. MOJO

Choose Member's Mark if you want more store-brand choices and consistently low prices. Choose Kirkland Signature if you care about premium quality and don't mind paying a little more for it. The Interview Guys

Kirkland Signature quality: Consistently rated higher than store brands. Greenmo

Verdict: Costco wins. Kirkland Signature's documented manufacturing partnerships with premium national brands create a private label quality standard that Member's Mark — which is genuinely good — does not consistently match. The member who buys Kirkland batteries, coffee, foil, and protein supplements is buying products manufactured by the recognized leaders in each category. This is Costco's most commercially defensible competitive advantage.

Round 4: Gas — Pricing and Payment Flexibility

Both clubs offer gas prices significantly below market rates:

Both clubs typically offer gas prices 10-30 cents below local stations, making gas alone a potential reason to join. At 15,000 miles/year, gas savings alone can exceed the basic membership cost. Greenmo

The pricing advantage is comparable between the two clubs — both typically price 10 to 30 cents per gallon below the market rate for the area. The difference that matters more than the price differential is payment flexibility.

Costco gas stations only accept Visa (plus debit, cash, and Costco Shop Cards). If you carry Mastercard or Amex, you'll need a Visa specifically for Costco gas. Sam's Club accepts all major credit cards at gas pumps. Greenmo

The Costco Visa exclusivity at the gas pump is one of the most consistently cited practical limitations of Costco membership — members who do not carry a Visa card as their primary credit card must either use cash, debit, or the Costco Anywhere Visa specifically for gas purchases. Sam's Club's acceptance of all major credit cards eliminates this friction entirely.

Verdict: Draw on price. Sam's Club wins on payment flexibility. The per-gallon savings are comparable. Sam's Club's payment flexibility advantage is meaningful for members who do not want to carry a Visa specifically for Costco gas.

Round 5: The Checkout Experience — Sam's Club's Scan & Go Advantage

Sam's Club's Scan & Go app is a standout perk — you can scan items as you shop and skip the checkout line entirely. On busy weekends, this feels like cheating (in the best way).

Costco's app is solid but doesn't offer a similar friction-free checkout option. If speed is your love language, Sam's Club wins here. The Interview Guys

Sam's Club's Scan & Go app — which allows members to scan items with their phone as they place them in the cart and pay through the app before exiting, bypassing checkout entirely — is the most commercially impactful technology differentiation between the two clubs. The Scan & Go experience on a busy Saturday afternoon is genuinely transformative: no checkout queue, no waiting, exit through a dedicated Scan & Go lane.

Costco's 2026 prescan technology — where employees scan items in your cart while you wait in queue — addresses the same checkout speed problem from a different direction, using employees rather than member self-scanning. The Costco prescan generates impressive 8-second payment times at the terminal. The Sam's Club Scan & Go eliminates the payment terminal step entirely.

If speed is your love language, Sam's Club wins. Sam's Club Scan & Go, or "scam and go" as some call it — is a no-brainer for avoiding long lines at Costco. MOJO

Verdict: Sam's Club wins. Scan & Go is the most mature member-facing technology advantage in the warehouse club industry as of 2026. Costco's prescan technology is catching up but has not yet delivered a comparable self-directed experience.

Round 6: Food Court

Costco's food court — the $1.50 hot dog combo that has not increased in price since 1985, the $1.99 pizza slice from an 18-inch pie, the $4.99 rotisserie chicken at the back of the store, and the Caramel Churro Sundae that generated viral social media coverage upon its April 2026 launch — is an institutional cultural phenomenon. Eightx

"The hot dog and the chicken bake are some of my favorites. I really enjoy the smoothies too. Sam's Club feels more like a concession stand." MOJO

Sam's Club's food court does not generate equivalent enthusiasm or equivalent viral social media content. The pricing is competitive, the offerings are reasonable, but the institutional mythology that surrounds Costco's food court — the decades of price stability, the $4.99 rotisserie chicken loss leader, the cult following that each seasonal food court addition generates — is simply not present. Eightx

Verdict: Costco wins, and it is not particularly close. The Costco food court is a cultural institution. The $1.50 hot dog is a commercial commitment that has not changed in 40 years. The Sam's Club food court is a good, inexpensive quick-service option. It is not a cultural touchstone.

Round 7: Pharmacy

Both clubs offer excellent tire programs with comparable pricing and included services. You don't need a membership to use the pharmacy at either club. Greenmo

Both Costco and Sam's Club pharmacies operate under the federal law that requires non-member access to prescription medications — giving both clubs equal access credentials for non-members.

The pricing advantage at the pharmacy counter varies by medication. Costco's Member Prescription Program (CMPP) — which extends member pricing to hundreds of medications including pet prescriptions — is broadly comparable in scope to Sam's Club's pharmacy program.

Perks: Sam's Club has better pharmacy discounts for seniors. Sam's Club's Plus membership includes specific senior-focused pharmacy benefits that Costco's program does not directly match. Greenmo

Verdict: Draw, with slight edge to Sam's Club for seniors. Both pharmacies deliver meaningful savings over CVS and Walgreens. Sam's Club's senior-specific pharmacy benefits give it a narrow edge for that demographic.

Round 8: Store Experience and Atmosphere

Costco stores feel premium: wider aisles, better lighting, newer fixtures. This isn't vanity — it affects shopping speed and product quality perception. MOJO

I come away from Costco with a full cart of products every time, but with Sam's, I usually only find a few handfuls of products that I felt good about purchasing. MOJO

The warehouse experience quality — the store layout, the product curation, the sample station energy, the discovery feeling — consistently favors Costco in member qualitative assessments. Costco's treasure hunt atmosphere, the authentic discovery energy that generates the social media content and the member loyalty, is a genuinely difficult institutional quality to replicate.

Verdict: Costco wins. The Costco warehouse experience is a competitive advantage that extends beyond product selection into the emotional relationship members have with the institution.

Round 9: Employee Treatment

Costco pays and treats its employees better, which makes me feel more positive about being a customer. MOJO

Costco's 93 percent one-year employee retention rate, $31.90 per hour top-of-scale wage, and comprehensive benefits package represent the most generous workforce investment in American retail. Sam's Club — as a Walmart subsidiary — operates under a different compensation philosophy, with wages and benefits that are generally below Costco's standard.

For members who factor employee treatment into their consumer choices — who consider the institutional treatment of workers a dimension of their own ethical consumer identity — this comparison consistently favors Costco.

Verdict: Costco wins significantly.

The Verdict: Which Club Is Right for You?

Choose Costco if: You prioritize product quality, love Kirkland Signature, don't mind lines, and have a Visa card for gas purchases. Choose Sam's Club if: You prioritize low prices, value convenience features like Scan & Go, want flexible payment options, or already use Walmart services. Choose both if: You have locations for both nearby and want maximum flexibility. Greenmo

Choose Costco if:

Product quality is your primary priority
Kirkland Signature's documented manufacturing partnerships matter to you
The food court experience is part of your membership enjoyment
Employee treatment is a factor in your consumer choices
You shop less frequently but spend more per visit

Choose Sam's Club if:

Lower membership fee is important
Scan & Go checkout technology changes your weekend experience
You primarily shop national brands where Sam's Club's pricing advantage is consistent
You carry Mastercard or American Express as your primary card
Convenience and lower per-unit grocery pricing are your top priorities

Consider both if: You have easy access to locations of each and want the maximum selection flexibility — the combined $115 basic membership cost gives you access to both ecosystems with the freedom to choose whichever has better pricing or selection on any specific shopping trip.
