Sams Club vs Costco is the ultimate warehouse showdown for budget-conscious shoppers. Both clubs promise bulk savings, exclusive perks, and members-only pricing. But the details matter more than the marketing. Membership fees, rewards programs, return policies, and gas discounts all vary between the two.
Choosing the wrong club could cost you hundreds per year. Choosing the right one could save you even more. This guide breaks down every major policy side by side. We’ll compare real numbers, not vague promises. Whether you’re feeding a family of six or stocking a small business, the Sams Club vs Costco debate deserves a closer look before you commit your annual fee.
Sams Club vs Costco: Membership Fees and What You Actually Get
The first cost to compare is the membership itself. Sam’s Club offers two tiers: Club at $50 per year and Plus at $110 per year. However, both tiers increase on May 1, 2026. Club jumps to $60 and Plus to $120. Costco’s Gold Star membership costs $65 per year. The Executive tier runs $130 per year. Sam’s Club is cheaper at both levels. The basic tier saves you $5 annually. The premium tier saves you $10.
But cheaper isn’t always better. Costco’s Executive membership caps its 2% reward at $1,250 per year. Sam’s Club Plus caps its 2% Sam’s Cash at $750 per year. If you spend more than $37,500 annually, Costco’s higher reward cap pays off. For lighter spenders, Sam’s Club’s lower fee wins. The Sams Club vs Costco membership decision depends entirely on your annual spending volume.
Rewards Programs and Credit Card Perks
Both clubs offer co-branded credit cards that stack with membership rewards. Here’s how they compare:
| Feature | Sam’s Club Mastercard | Costco Anywhere Visa (Citi) |
|---|---|---|
| Gas (own stations) | 5% back (first $6,000/yr) | 5% back ($7,000/yr cap) |
| Gas (other stations) | 5% back (first $6,000/yr) | 4% back ($7,000/yr cap) |
| Dining | 3% back | 3% back |
| In-store purchases | 3% back (Plus members) | 2% back |
| Everything else | 1% back | 1% back |
| Annual fee | $0 | $0 |
Sam’s Club’s card gives 3% back on in-store purchases for Plus members. Costco’s card only returns 2% in-store. That difference adds up on big bulk runs. However, Costco’s gas spending cap is higher at $7,000 versus $6,000. Both cards charge no annual fee. When comparing Sams Club vs Costco credit cards, Sam’s Club edges ahead for frequent in-store shoppers. Costco wins for heavy gas buyers.
Sam’s Cash never expires while your membership is active. You can redeem it in-club, online, or toward renewal fees. Costco issues its Executive reward as a check once per year. You’ll receive it about three months before your renewal date. Sam’s Club’s instant-access model is more flexible for most shoppers.
Return Policies and Price Adjustments
Both clubs offer generous return policies. Most items can be returned anytime with no time limit. No receipt is needed at either store. Your membership card tracks every purchase. Electronics have a 90-day return window at both clubs. The big difference is cell phones. Sam’s Club gives you just 14 days. Costco gives you 90 days. That gap matters when you’re testing a new phone.
Price adjustments show a clear winner. Costco offers a 30-day price adjustment window on most purchases. If an item drops in price within a month, you get the difference back. Sam’s Club only gives you 8 days. That’s less than a third of Costco’s window. Neither club price-matches competitors. In the Sams Club vs Costco return policy comparison, Costco’s 30-day adjustment is a standout advantage.
Gas Savings and Grocery Value
Gas stations at both clubs typically save you $0.10 to $0.25 per gallon versus nearby stations. Costco occasionally hits $0.30 below market prices. For the average driver using 600 gallons per year, that translates to roughly $120 to $180 in annual savings. Gas savings alone can cover a basic membership at either club. Stack the 5% credit card cashback, and the Sams Club vs Costco gas comparison becomes even more compelling.
Store brands tell an interesting story. Costco’s Kirkland Signature has a premium reputation across roughly 400 products. Sam’s Club’s Member’s Mark covers over 6,000 products. Member’s Mark toilet paper costs about 24% less than Kirkland’s equivalent. Shoppers rate it as sturdier too. Kirkland wins on items like olive oil and vodka. Member’s Mark wins on variety and value. The Sams Club vs Costco store brand battle is closer than most people think.
Pro Tips and Insider Strategies
Shopping communities share strategies that maximize savings at both clubs. Sam’s Club’s Scan & Go app lets you scan items with your phone and skip checkout entirely. It’s available at every location. Costco is still testing self-checkout in only 27 stores. If checkout speed matters to you, Sam’s Club has a clear lead. The Sams Club vs Costco technology gap is significant here.
Time your membership purchase carefully. Sam’s Club frequently offers $30 first-year memberships. Right now through April 23, 2026, new members pay just $30 for Club tier. That’s 40% off before the May 1 price increase. Costco runs periodic Groupon deals bundling a Gold Star membership with a $45 Shop Card. That drops the effective first-year cost to around $20.
Don’t overlook pharmacy savings when evaluating Sams Club vs Costco. Sam’s Club offers 10 select generic medications for $0. Costco’s Member Prescription Program saves up to 80% on prescriptions. Costco’s hearing aid center sells pairs for $980 to $1,700 versus $2,000 to $8,000 at typical retailers. Sam’s Club Plus members get free prescription delivery and 50% off tire installation. Both clubs offer optical services with competitive pricing on exams and eyeglasses.
