When making purchases at Costco warehouse stores, you have the following options for making a purchase:
- Checks (Picture ID may be required)
- Debit cards
- Visa credit cards only (no American Express, Discover, or Mastercard)
- EBT cards / food stamps
- Costco Cash Cards (Costco gift cards)
As noted above, Costco’s exclusive credit card partner is Visa, and Costco only accepts the credit cards of its card partner if you want to pay by credit.
Purchases on Costco.com are different than purchases at a Costco warehouse location. Costco’s online site accepts Visa, MasterCard, and Discover, but not American Express. Costco Cash Cards can be used for online payment as well. No other form of payment is accepted online.
