I downloaded this app Wednesday, and I'm not gonna lie, and say that I know all the ins and outs yet. But I will tell you that I LOVE THIS APP! I just started my ThriftBooks account a couple days ago, and I ordered three books for $10, with FREE SHIPPING for the US! It's incredible. One of the books I had picked out was condition-wise classified as Very Good, but they upgraded it to Like New for free, because it was greener that way. And by downloading the app, I got a 15% off coupon. Also, for every $50 you spend on books, you get a $5 coupon. This thing is awesome! I can't believe I only just found this site/app. I just spent like half an hour adding things to my Wish-List. Something that I really like about this app is that when you add a book that is out of stock to your wish list, it shows you how often they get a copy of that book and how many other people are watching the item. I really really want you to check it out! I'll be sharing picture, probably on Twitter, I'm sort of a Twitter-holic, (@3714Bookdragon) of the books when they come. I can't wait to share with all of you.
