Today, I returned a book I don’t need for a college class anymore to get a full refund and was curious what I’d get if I was to sell it back the used (it’s a few days into the semester). I asked and he pulled up a webpage, scanned the barcode, and it pulled the book’s page up, listing the national price for about $10 (the book cost $98.50 USED). He said it was simply because of supply and demand obviously, but also because he was trying to get books out the door, not in. The big graphic on the page was “ta online” which ends up being a database service from MBS Systems (http://www.mbsbooks.com/Systems/Online/TAonline.htm). How can I gain access to a database like this or any system that can give me insight as to what bookstores are willing to pay to buyback books? Thanks for any help.
