First off, let me describe what this website does. I created this site for the general public to use as a tool to look up current buyback prices for all textbook buyback sites. An ISBN is entered and the program automatically pulls prices from affiliates and the best price being at the top. Customer are then able to sell their books or textbooks at the highest payout. The problem I'm having is some sites don't use API. Would there be someone with recomendations on a scrapper that would grab the prices for the affiliates that don't use an API? http://bookquoter.com
