Rebate cards let card users earn money by spending money. A crazy concept, but it works and more and more card issuers are jumping in with their own "get cash back" cards. Rebate or Cash Back card users receive more of a percentage of cash back for purchases like groceries, gas, and other everyday items. Rebate cards don't usually offer much more than 5% cash back on purchases. Caution: If you plan to spend big with your rebate card, check application terms for rebate caps.
