Oh I saw those, they were rad.
Yeah many people do. I just loaded up all my quality doubles, found a vendor that had something I wanted and asked if he took trades. Ended up getting a Saturn Bomberman in minty shape just before the end of show yesterday. I am also part of a community group that organizes trades and deals ahead of time which helped me build up even more funds to spend this weekend. I'd love to attend another Expo, I've only ever been to Portland's, but it's a ton of fun and I highly recommend it.
