Rebates will be earned at a rate of 3% for all purchases made at participating Gulf locations and 1% on all other purchases made anywhere else (excluding purchases made at any merchant that sells gasoline other than Gulf branded gasoline) provided the account is open and current at the time of purchase. There is no maximum rebate allowance for purchases at Gulf branded locations. Rebate accumulations will be reported monthly on your billing statement. Each time you accumulate at least $20 in rebates, a gift card will be automatically mailed to you. Allow 60 days for delivery. Rebates are not transferable and points accumulated will expire after 24 months if not redeemed. Should you accumulate a negative balance, any outstanding Gulf gift card will be reconciled against your existing point balance to put the gift card at $0.00 balance. Gulf gift cards are honored at any participating Gulf branded location in the USA. The Gulf gift card or any other rebate method is offered by the Program and is not an obligation of Barclays. Any disputes concerning rebates will not affect your payment obligation to Barclays on your account. You will not earn rebates if your account is not in good standing. Any tax liability resulting from the Program is the cardmembers responsibility. Barclays is not responsible for any dispute from joint cardmembers or authorized users relating to the rebate Program. Any discrepancies in rebates earned must be brought to Barclays' attention promptly, but in no event later than 60 days from the date of the transaction or the billing statement for which an adjustment is sought.
