I love the idea of the Book Nook. I am an avid reader who isn't a huge fan of the library system available to me. Therefore, I end up buying almost all the books I read. This ends up being very costly so the idea of being able to buy books at a cheaper cost AND being able to sell my own books is great. The Book Nook sells books, cds, and comics for 60% of their cover price. I have found many books that are still on the best sellers list and look brand new. You also can find some older books with much cheaper cover prices which end up being quite the bargain. The Book Nook then will buy any book they think will sell from you for 30% of the cover price. It's not a ton but better than you'd get at a garage sale and a lot less work than Ebay.
