I haven't heard of it but it sounds interesting! I have gotten to where I buy all my books from Amazon now. I read so much and go through so many books, and it's just a lot less expensive that way, even with shipping and handling they are usually less than what you'd pay at a book store. I use my check card so I don't have to pay interest on a credit card for what I order. I don't really care if the books I get have been used or not, as long as they are readable, so I often buy used too. I see you can get that one for 10 dollars on Amazon. I may have to order that next!
