One of the best ways to save money is buying things when a store or company offers a rebate on an item. Years ago, the rebates would come in the form of a paper check that you take to the bank and deposit. Lately, more and more rebate vendors are sending rebates as a prepaid debit card.
While prepaid debit cards or gift cards with a Visa / Mastercard / Discover / AMEX logo work like any normal debit card, they can become a hassle when you have small amounts of money on them.
