From another board who borrowed it from andther board:
Free $15 gas voucher for 800# call. Copied from an insert I got with my credit card bill: Get your free $15 in gas vouchers. No kidding. Just call 1-800-617-1090 and listen to information about an insurance offer. That's all. Now here's the extra info I added: They ask you to enter your VISA card first 4 digits but I just pressed any 4 numbers and got a live operator. She asked me what state I am in. When I told her NY, she said the insurance offer is not for NY but I would get the voucher anyway. Then when you buy gas, you mail in the voucher and receipt for a rebate.
i am on the phone with them now
