Costco sells gas for $0.10-0.15 less per gallon than retail stations, but only to members who pay annual dues. Blueprint For Financial Prosperity claims to have found a way for non-members to access the bargain gas…
Normally, you have to swipe your Costco Card or the American Express Costco TrueEarnings card in order to authenticate in their gas station systems. It appears that you can simply use any American Express card in the authentication phase because the American Express Costco TrueEarnings card is just an AMEX with a Costco bar code.
The trick definitely works in Maryland, but not in New Jersey or Oregon. Would you fill your tank at Costco, or are the ethical considerations enough to keep you at your local station?
