I agree. Thank-you Amazon, for how would anybody have dreamed of knowing the stories, let alone see the book, if not for this company? They would have been hidden away, lost forever, to be collected and prized, but never seen, loved or appreciated. This way, every child and Potter fan can truly enjoy the books, simply by reading from a page. A wonderful gift, and completely free. Thank-you Amazon.
Sure, money to charity with auction. Books being sold, more money to charity.
Only thing is that I'm Dutch and the charity is more an English thing, still it helps "the world" nonetheless I suppose. On a personal note I always prefer "animal" charities above "human" charities. Humans aren't extinct yet :). (we will be in 300-400 years anyway)
