Sam's Club accepts most major credit cards, but the rules depend on whether you shop in-warehouse or online
Sam's Club takes Visa, Mastercard, American Express, and Discover at warehouse locations and on their website. Costco's membership model is different — they restrict payment methods more tightly — but Sam's Club gives you flexibility across all four major card networks. The one real limit is that Sam's Club does not accept Diners Club or store credit cards from other retailers.
If you have a Sam's Club Mastercard, you can use it anywhere Mastercard is accepted, including at Sam's Club itself. The membership card and the payment card are separate things, so you need both to shop there.
Key Takeaways
- Sam's Club accepts Visa, Mastercard, American Express, and Discover at all warehouse locations and online.
- The Sam's Club Mastercard earns rewards on purchases but works like any other Mastercard at checkout.
- You must have a valid Sam's Club membership card in addition to your payment card to enter the warehouse.
- Online orders can be paid with the same credit cards accepted in-warehouse, plus PayPal on the website.
Credit cards that work at Sam's Club warehouses
At the register in any Sam's Club warehouse, you can pay with Visa, Mastercard, American Express, or Discover. The cashier will process your card the same way any other retailer does. You do not need a Sam's Club-branded card — your personal Visa from your bank works just as well as anyone else's.
Sam's Club also issues its own Mastercard through Synchrony Bank. This card earns cash back on Sam's Club purchases and gas, plus rewards on other spending. It functions as a regular Mastercard everywhere, but you can only use it at Sam's Club if you are a member. The membership requirement applies to all payment methods, not just the Sam's Club card.
Diners Club is not accepted. Store credit cards from Target, Walmart, or other retailers will not work either. If your only card is one of those, you will need to bring a different payment method or add a Visa, Mastercard, American Express, or Discover to your wallet.
Paying for online orders at Sam's Club
On the Sam's Club website, you can pay with the same four credit card networks: Visa, Mastercard, American Express, and Discover. You can also use PayPal if you have an account, which links to your bank account or card on file there.
Online orders still require an active Sam's Club membership. When you log into your account on the website, the system checks your membership status before letting you proceed to checkout. If your membership has expired, you will see a message asking you to renew before you can complete the purchase.
What to do if your card is declined at Sam's Club
If your credit card is declined at the register, the most common reasons are insufficient funds, a fraud alert from your bank, or an expired card. Call your card issuer's customer service number on the back of your card to find out why. Many banks flag unusual purchases as a security measure, and a quick call can clear it so you can try again.
If you are using a debit card instead of a credit card, some banks place temporary holds on large purchases. Sam's Club transactions can be substantial, so your bank may be holding the funds as a precaution. Your bank can release the hold, or you can wait 24 to 48 hours for it to clear automatically.
If you do not have a working credit or debit card with you, Sam's Club warehouses do not accept cash, checks, or digital wallets like Apple Pay or Google Pay at this time. You will need to leave and return with an accepted payment method.
Sam's Club Mastercard rewards and benefits
The Sam's Club Mastercard earns 5% cash back on gas (up to $6,000 per year, then 1%), 3% on dining and travel, and 1% on all other purchases. The card has no annual fee, and the cash back posts to your account monthly. You can use the rewards to pay your statement balance or redeem them as a statement credit.
The card is issued by Synchrony Bank, not by Sam's Club directly. You explore through Synchrony's website or in-warehouse at the membership desk. Approval decisions usually come within minutes if you explore online, or you can get a temporary card number to use right away while you wait for the physical card to arrive.
The Sam's Club Mastercard is a credit card, not a debit card, so you carry a balance and make monthly payments. It reports to the three major credit bureaus, which means on-time payments help your credit score and missed payments hurt it.
Payment methods Sam's Club does not accept
Sam's Club does not accept cash, personal checks, or digital payment apps like Apple Pay, Google Pay, or Samsung Pay at warehouse locations. Online, you cannot use digital wallets either, though you can use PayPal if you have an account.
Prepaid cards and gift cards from other retailers are not accepted as payment. You can use a prepaid Visa or Mastercard if it is branded as one of those networks, but a generic prepaid card without a Visa or Mastercard logo will be declined.
Sam's Club does not accept payment plans or buy-now-pay-later services like Affirm or Klarna at checkout. If you want to split a purchase into installments, you would need to use a credit card that offers that feature through your bank or card issuer.
Membership card versus payment card
Your Sam's Club membership card and your payment card are two separate things. The membership card proves you have paid for access to the warehouse and shows your membership number and tier (Gold Star or Plus). The payment card is what you use to pay for the items you buy.
You must present your membership card at the entrance to enter the warehouse. At checkout, you present your payment card. If you forget your membership card, you can give the cashier your phone number or email address associated with your account, and they can look you up in the system. You cannot enter the warehouse without proof of membership, even if you have a valid payment card.
If you have a Sam's Club Mastercard, it is a payment card only. It does not replace your membership card. You still need to bring your membership card to the warehouse every time you shop.
Frequently Asked Questions
Can I use my Sam's Club Mastercard outside of Sam's Club?
Yes. The Sam's Club Mastercard is a regular Mastercard, so you can use it anywhere Mastercard is accepted — restaurants, gas stations, online retailers, and more. You will earn 1% cash back on non-Sam's Club purchases, compared to 5% on gas and 3% on dining and travel.
What if I do not have a Sam's Club membership but want to pay with a credit card?
You cannot shop at Sam's Club without an active membership, regardless of what payment method you have. You would need to purchase a membership first. Memberships start at the Gold Star level and can be bought at the warehouse entrance or online.
Does Sam's Club accept American Express gift cards?
Yes, if the gift card is branded as American Express. Sam's Club accepts all four major card networks, including American Express. The gift card will work the same way a personal American Express card does at checkout.
Can I use multiple credit cards to pay for one purchase?
At warehouse locations, you can split payment between two cards if you ask the cashier. Online, the checkout system typically accepts only one payment method per order. If you need to split an online order, you would need to place two separate orders.
What happens if my credit card expires while I am shopping?
An expired card will be declined at checkout. The expiration date is printed on the front of your card, and the system checks it during processing. If your card is expiring soon, contact your card issuer to request a replacement before your next shopping trip.
