Nope I don't buy books, I can't learn that way.
I have received one book from Amazon though (due to a mistake). I bought a game off Amazon and the box arrived on Sep 8th, 2001. I opened it up to find a book about Showbiz. It turns out the book was actually supposed to goto a law firm in World Trade Center tower #2. Amazon was going to have me send it back in but a few days passed and the towers collapsed, then they told me just to keep it and they'd send me another copy of the game I was supposed to receive.
