Today Amazon has Up to 85% off New York Times Bestsellers! I found books for as low as 99¢, including children's books.
I couldn't get past the amazing reviews so I'm reading this book right now, but I'm just a few chapters in - so far, so good. If you prefer a "real" book instead of a Kindle book, click on the book links you can see new & used paperback and hardback prices too - starting at only $0.01 + $3.99!
