Best credit card to use at Costco.
Wholesale Club
Costco Wholesale runs about 600 warehouses worldwide and a sizable online catalog at costco.com. The pricing model revolves around member-only bulk buying, so card choice matters most for people running weekly grocery and gas trips through the warehouse. Two quirks worth knowing: Costco accepts only Visa cards in-warehouse (no Mastercard, Amex, or Discover), and Costco gas pumps code as wholesale clubs — not gas — so a 5% gas card will not trigger at the pump here.
