I'm selling off my collection of Magic:The Gathering cards and accessories on eBay. It's a pretty big collection that's been gathering dust for the past year or so. I'm sure it's worth at least three zillion dollars if you were willing to price and sell the cards individually. If you're looking for a cheap way to get into the game, check it out here.
I'm also auctioning off my old World of C++ video course. Read more about it here. Current asking price is 25 cents!
