Making money while shopping
Get a debit or credit card that "pays back" in points or cash. Use the card to shop, eat out, pay for gas and bills. Check your expenses to make sure that the balance on the card does not exceed the monthly balance in your checking account and then pay off your credit card as soon as the bill comes. That way, you won't pay a single penny for interest and instead have the bank or credit card company pay YOU for using their product.
