Textbooks-who sells discount books and software for a non-profit and a college?

If you are looking for cheap textbooks, then look no further than bigWords, a textbook search engine that searches all the online textbook retailers and rental sites to find you the best prices. And at the end of the semester you can use them to search for resellers to sell your book to. All the search results are organized by price so you can buy your books for the lowest prices and sell them back for the highest.
