I don't know where you guys buy your books - maybe at your local bookshop, maybe at amazon, or like I do most of the time somewhere on the Internet, but NOT at amazon (out of personal antipathy and my paranoia concerning my data..).
So, there's this really beautiful home page where they offer a curiously wide (and partly kind of weird) selection of books absolutely cheap and I really want to share this one with you. Most of the books are used, but all I got are in pretty good condition.
The guys behind all this are situated in Austria (you know, the country where there are no kangaroos, unlike Australia) so they offer mostly books in German.
But if you're interested in that, check it out!
