You may redeem GasBack® by using your GasBuddy™ Mastercard® Credit Card on fuel purchased at the pump, paid as a statement credit. Using your GasBuddy™ Mastercard® on fuel purchased at the pump initiates redemption on your available balance in your GasBack account. The entirety of the GasBack account balance earned with the GasBuddy Mastercard Credit Card will be redeemed unless the transaction size is smaller than the GasBack account balance. Once initiated, GasBack statement credits may take up to 10 business days to post to your account.
