Amazon has a new Textbook Rental Program that lets you choose the number of days you need the textbook and then you’ll only pay for each day that you use the textbook.

• Great savings: Save up to 80% off the list price of the print textbook
• Pay only for the time you need: Choose a rental length between 30 and 360 days and pay only for the exact time you need a book. Extend your rental for as little as one day or convert to purchase
• Rent once, read everywhere: Rent and read tens of thousands of textbooks on PC, Mac, Kindle, or your mobile device
• Keep your annotations: Access your notes and highlights anytime, even after the rental expires, at kindle.amazon.com

You can download a free Kindle reading app for your PC, Mac, iPad, iPhone, Android device, Windows Phone 7, Blackberry, or Kindle.
