I had bought an airplane ticket online from cheapoair and the shoppers advantage card was offered as a way to get a $20 rebate, which I never recieved. All you had to do was pay a $1 fee for the service and could cancel at anytime within 30 days to not be billed each month. I did call and cancel this subscription within the 30 days, and two months later was billed for $16.99. I am livid. This has resulted in a $35 fee from my bank, and it is not an authorized payment. I have contacted the BBB, my bank, and Billguard.
