I was in a hippie sandwhich shop here in Austin and saw a 1st edition Star Wars RPG HC. The rest of the bookshelf was covered with paperbacks that I guess people left in the store and never came back for. I asked the smiling sunshine dreadlock girl behind the counter if I could take a book, if I promised to read it and she said, "Of course you can!"
So I grabbed it, said thanks and left. The very next day I found a copy of the sourcebook in half price books for $10.
If only Lottery tickets worked this way for me.
