Well what you know about that? Every once in a while you toast falls on the floor butter side up and you know it's going to be a lucky day. I went to my favorite online bookstore-Thriftbooks- and bought both books you mentioned for $10.01. Well, one was free because I had points and the other one was used in a paperback but not too shabby, huh ? find the book you want and check it out at thrift books. Lots of times you can save some serious coin.
