Credit cards to use at Costco stores - U.S.
As of June 20th, 2016 Costco stores in the United States accept only those credit cards that use the Visa payment network. (Prior to that date, Costco stores accepted only those credit cards that used the American Express payment network.) Costco has a special relationship with Citibank in the U.S., but any Visa card can be used in-store. Below you'll find a number of Visa cards to choose from. You can further narrow them using the filters and preferences and see which Visa cards will reward you more, not just for your spending at Costco, but also for whatever portion of your regular monthly expenses you enter.
