Query: Unfair price change

About one week after I bought the Kindle, they dropped the price $50. I understand Amazon's policy of not changing prices in most cases, but I do not think it applies here. Since the Kindle is their toy, the price was not based upon the supply. It is arbitrary.So I am angry about this and it has reflected how I feel about the device. Otherwise, I am pleased with it, except for the incidents with the cover. When I went to purchase a cover, I read that the covers can actually break the Kindle if opened from the back. How can such a poorly designed product be sold? What is going on here!?!Q
