This may be a dumb statement but I really don't see the use in them. Perhaps this is because I don't understand why they're even used. I mean isnt' it easier to just make it an instant rebate? No hassle, the price is as it appears and no company has to ship you money back. With the mail in rebate it's the manufacturing company, for example, say EVGA that'd give you the money or is it the retailer like, say ZipZoomFly? Maybe I'm bias because I've been screwed over with rebates the expired between the time that I got the item and immediately sent in for the rebate, not getting any money back, but it just seems like there should be a better way. In this day in age mailing money strikes me as a tad odd. Anyone care to enlighten me?
