Query: A great book.

This book is real great. If you haven't seen the movie, I think that is well done, also.I really just wanted to comment on how you can buy a used hardcover of this for UNDER A DOLLAR, and yet you have to pay $12.99 for the kindle edition....I'm glad that my kindle was a gift, so I don't feel obligated to spend 13 times the amount of a real book, to have a paperless edition.This is where kindle book pricing does not make sense to me.... If the kindle edition was, say, $4.00 or even $7.00 or so, I would have spent that. Why? I do like my kindle. But the stubborn high prices on ebooks is actually swaying me to NOT buy ebooks, and still even save money by purchasing used for UNDER A DOLLAR.Haha, sorry if this is confusing. I realize that ebook prices are not always Amazon's setting, so no complaints there. Just a general WTF, why is it SO EXPENSIVE rant.
