Who doesn't love books? Who can't afford all the books they'd like to read? If you're serving in some far away place you probably order all your books online. But Amazon doesn't always have the lowest price on your next great read.
Check out Booksprice a handy book-seller comparison tool. Enter your book's title, author or ISBN number and Booksprice will return a gazillion different purchasing options, all sorted by price.
You'll see how Amazon compares with Barnes & Noble against Ebay and Half.com
Of course, you still have to have that friend or family member send your new book to you in the latest care package, but at least you got a great deal up front.
