Yes, within the savings section of the app you can pay any outstanding balance you may have on your account with a credit card.
When you pay a balance by credit card we charge a fee of $0.30 + 2.9% of the outstanding balance. For example, if you pay a balance of $50 with a credit card we will charge a fee of $.30 plus $1.45 for a total fee of $1.75.
If you paid by credit card and did not update your bank information, you will need to contact support to reactivate your card. Fill out a ticket here as follows:
Select Pay with GasBuddy™ > Outstanding Balance
Under Outstanding Balance select Pay by Credit Card
Please note in the subject that you need to reactivate your card.
