BookBurro
If you are a book reader and you browse with Firefox, and you should be, there is a handy, free extension which can save you some time and money.
Firefox extension Book Burro searches for the lowest price on the book you’re looking at buying.
Book Burro is a Web 2.0 extension for Firefox. When it senses your are looking at a page that contains a book, it will overlay a small panel which when opened lists prices at online bookstores such as Amazon, Buy, Half (and many more) and soon whether the book is available at your library.
