The world’s largest online retailer just so happens to be one of the largest textbook outlets on the Net. Besides selling new and discounted books through its third-party marketplace, Amazon features its own textbook section that offers up to 80 percent on rentals and purchases. The retail giant has a special student program called “Amazon Student,” which blesses members with discounts and promotions, plus six months of free two-day shipping with an Amazon Prime account. And if viewing textbooks on your laptop screen wasn't satisfying enough, Amazon has announced plans to use its Kindle app to push e-textbooks, giving you the opportunity to view textbooks on your smartphone and tablet. Ahhh, the days of hauling heavy books in your Jansport are almost over people.
