This one's quick and easy. If you've got any flavor of American Express card in your wallet, do what I just did. Grab the card, dial the phone number on the back, and tell the customer service rep that you want your card converted into a Blue Cash Card. The conversion happens on the spot. And from then on, every time you use that card to pay for something you'll get 3% cash back on groceries, 2% cash back on gasoline and some other retail stuff, and 1% cash back on everything else. And you won't be paying an annual fee on this card, either.
If you don't have an American Express card, it could even be better. Call them up or go on the web, get yourself a Blue Cash card, and American Express will give you a $100 bonus if you use the card to pay for $1000 worth of anything in your first 3 months.
Every dollar helps, you know. ;)
