I have this card, and the 2-5% depends on how much else you put on the card. I normally get the 5% back since its my main card
I really have no problem with the card. I like AAA as a company; I like their roadside assistance; I like the auto insurance company.
My only problem with the card is that BofA just recently bought MBNA, so the card is now a BofA card. But I haven't had any issues with the switch. I just don't like BofA.
The other nice thing about the AAA gas card is that if you use AutoClub's travel service and use that card, you get excellent deals.
