Im advising everyone to not shop at Best Buy. Its really a complicated story, but it comes down to them not wanting unwanted or "Devil" customers to shop their stores any more. "Devils" would be people who buy stuff only when they have it on sale for a deep discount and also people who send in rebates. They want "angels" to continue to shop there, people who walk in and buy stuff no matter what the price is and dont send in rebates. As I said, its kinda more complicated than that, but if you want to know more you can read this article
