I was checking gas prices today and its up to $4.25 where I live. I did notice that Costco gas is cheaper, by nearly twenty cents per gallon. While I do shop at Costco, my local one does not have a gas station. However, I will be driving by another location later today and I can stop there and fill up my 25 gallon tank. So, my question is, what types of payments can I do at the pump? Is it the same as inside the store, cash or Amex? Can I use my regular visa at the pump or not? Thanks.
As Costco is, by and large, an unattended station, they do not accept cash.
They only accept AMEX cards, PIN-based debit cards, and their in-house Cash Card.
