Don't recommend unless you have cash. Used $60.00 prepaid credit card for $37.50 gas. Receipt stated used all $60. Told cashier so he recalculated and correct receipt was issued stating $22.50 change. Asked if this was on the card or should I receive cash back. He said it was definitely back on the card. Guess what? The next station would not honor invalid card, no funds. Too bad I was traveling through DC driving from Myrtle Beach to NY. Exxon has not responded to email inquiry.
