What forms of payment does Costco accept?

Q. What are my options for paying at Costco?

Adam answers:

That depends on if you are talking about paying at a Costco warehouse store or online at Costco.com:

  • At a Costco store: you may pay with cash, a check, a debit card, a Costco Cash Card, or with an American Express card (including the Costco TrueEarnings American Express card). At the moment American Express is the ONLY credit card accepted in Costco warehouse stores in the United States. (Note that this will change on June 19th/20th of 2016 — the agreement between American Express and Costco will end on June 19th and, starting on June 20th, Visa will take over as Costco’s exclusive credit card partner, meaning only Visa credit cards will be accepted in Costco stores. At that time Costco will also begin to offer a Costco-branded Visa credit card in partnership with Citibank that replaces the current TrueEarnings Amex Card.)
  • On Costco.com: you can use just about any credit card — American Express, MasterCard, Visa, or Discover — as well as Costco Cash Cards.

Of note: if you don’t want to use American Express but want to use another credit card for in-store purchases, you could buy Costco Cash Cards online with your credit card and then use those in store. It’s a bit of a pain as a workaround, but that’s up to you.
