If you're a book collector, you may or may not be aware of this. The excellent book "The Making of Episode I" by Laurent Bouzereau actually comes in two versions. A $40 hardback version and a $20 paperback version. I originally bought the paperback, thinking that was all there was, then found the hardback. B. Dalton allowed me to bring the paperback back and trade it in for the hardback. You could probably do the same if you were interested.
