lol Yeah, I have a little bit of trouble with keeping money in my wallet, too. ;D Libraries are probably the best bet, but I'm kind of snob about how a book is handled (if pages are dog-eared, spines are broken ...), so, I usually end up buying them. Bad me. heh
Oh, and I haven't read this one, but it looked promising enough for me to put it on my wishlist (in case you're interested).
