You know those economic stimulus rebate checks we're all (well, a lot of us) supposed to get next month? The whole point is to get people to buy stuff, right? Well, RadioShack figures that if you're going to be spending it anyway, you may as well spend it at RadioShack.

Customers who use their checks to pay for purchases above $50 between May 4 and July 12, 2008, will receive a 10 percent discount on their purchases. Any amount left over from the purchase will be placed on a Vision Silver Prepaid MasterCard, which can be used at any place that accepts MasterCard.

"While we would certainly love for them to spend everything at RadioShack, we understand other obligations may be necessary," said the company's executive vice president, merchandising, Peter Whitsett. "Fortunately, our offer gives them the best of both worlds: save upfront on their consumer electronics purchase and save the rest of the money for a later date. This is the kind of personalized solution that keeps our customers' best interests at heart."

Most taxpayers will be receiving $600 to $1,200, plus added amounts for dependents. That's a lot of coaxial cable.
