Apparently it's too late to return, but this summer I spent 74.50 on this book only to find that it is missing thirty-forty pages. In other words, it's a defectively bound copy. Maybe a good idea to flip through the pages of books received to make sure that you don't have a substandard copy.
Amazon's suggestion is that you can resell after thirty days, but obviously, I don't want to sell anyone a lemon...
