Frequently Asked Questions
Does the gas station brand matter?
Most cards reward “gas stations” as a merchant category. Brand doesn’t usually matter — it’s about the merchant code.
Does paying at the pump count?
Yes, pay-at-pump transactions typically count as gas station purchases for rewards purposes.
What about warehouse club gas?
Costco and Sam’s Club gas earns rewards as “warehouse club” not gas station — except on the Costco Anywhere Visa.
