"Bought a book from Capital Books and they sent me the wrong version even though I typed in the correct ISBN. When the book arrived, it had a receipt from Amazon.com with my name on it. I contacted Half.com and they sporadically sent out replys during the holiday to send the book back to a Captial book address . I sent the book back to an address that Capital books told me to which was different. Half.com replied "since you did not reply back, you cannot get a refund but if you want you can sell the book on Half.com. Do not use this site. A few dollars more, you can get the book from a more reputable comany like Amazon.com. I also stop using EBAY for the same reasons. Buy from them at your own risk!"
