As of 2014, Sam's Club accepts Discover, Mastercard, Sam's Club Credit and Walmart Credit in its stores. At SamsClub.com, it also accepts American Express and Visa credit cards as payment methods. However, American Express currently requires registration of all shipping addresses that do not match the customer's billing address.
Other payment methods Sam's Club accepts in its stores include cash, check, debit card, SNAP, Walmart Shopping Cards and Sam's Club Shopping Cards. With the exception of cash, all of these payment methods are acceptable at SamsClub.com as well. Members can use their Sam's Club Credit in Walmart but cannot use Sam's Club Private Label Credit at Walmart gas stations.
