Amazon Textbook Price Finder

I am interested in the used textbook section of Amazon. What I am looking for is a list that will show me these things: 1. The price of the used textbook to purchase on the Amazon marketplace 2. The price Amazon is currently paying to buyback that book ([login to view URL]). It does not matter what kind of textbooks or anything like that, in the end all I am looking for is a list of textbooks where I can make money by buying them used off the Amazon Marketplace, and then turning around and selling that book back to Amazon through their Textbook Buyback program. So, I will need to know which books have a small used selling price vs. their Textbook Buyback price. Is something like this possible, I am willing to pay$$$
