If you don't like download software for your Linux box, or you wanna buy cool bumper stickers for your car
which say "I stop for penguins" or a Tux plush, mug or shirt of Tux racing against Bill Gates, there's a real good website.

It has great books, and you can even get something like Mdk Linux 8.2 for US$5.99!
I also noticed it had a CD which had a load of sources for Linux software to use or compile.
