I might be asking for something that doesn't exist but I'm looking for an affiliate program that would easily allow us to display the lowest prices on the Internet for a product based on its ISBN. So let's say we have a book with an ISBN of 0743284003 (Michael Jordan's new book). We could list information for the book on the site and plug in an ISBN that would display the lowest prices for the product from other Internet retailers. Kind of the same as how BookFinder4U.com does it except that ideally we would like to be able to show those prices on our pages rather than directing them elsewhere to see the prices. I'm not sure if something like this exists or not. Does anyone know?
I think you will need to code that yourself. Sounds like a good idea if there are enough people searching that way. If the datafeeds from online book sellers contain the ISBN you would be well on your way. Cheers, Peter
