The use of rebate and rewards cards has grown rapidly. Costco for example sponsors a credit card (Costco Cash Rebate card) that give rebates on the cost of merchandise you buy with the card once you spend a certain amount. You usually get larger rebates on the sponsoring company's products and lower rebates on other card charges. Credit card solicitations promise cash, frequent-flier miles or points that will buy everything from hotel rooms to gas.
Tip: You'll get a good deal from a rebate card if you spend a lot, and if you pay your bill in full each month. If you carry a balance on the card, what you gain in rebates you will lose in the excessive interest charged by credit cards.
