They give rebates because, if the major institution, Sony, GE, Etc. Can hold onto your money for a couple weeks, the money, in the long run, compounded on all the other monies that the company is holding for other products, they can sit on those monies and collect interest on it.

So, the interest on $100 is not much. But the interest on $30million is.
Even at a low percentage for a short time.
