Back to School: Sell your textbooks on Amazon
The next time you want to sell your textbooks, look into doing it on Amazon rather than your campus bookstore.
Back in the day when I was in college (two years ago), I sold all my textbooks via Amazon and got back MUCH more than I did the previous semester at my campus bookstore. All you need is the ISBN and Amazon takes care of the rest: they post an image, figure out shipping, and market it for you. Yep - your book will now be seen all over the world, giving you a much better chance to unload a possibly outdated book (not all profs change their texts every quarter).
