Book Burro
At a Glance
Amazon isn't the only source for books. You can often save even more money by buying elsewhere. Book Burro, a Firefox extension, integrates with Amazon and searches your local library and other online bookstores to find you the cheapest price--which, if it finds the book at your library, is most likely zilch.
Note: This link takes you to the vendor's site, where you can automatically install the file into your Firefox browser.
