I found a new still in shrink wrap copy of NBA 2K for the Dreamcast in my local grocery store the other day. $1. Not a scarce game by stretch of the imagination but an interesting find considering the location.
Other stores in the chain used to rent games and videos. So they got a bunch of PS1 games and Dreamcast games in to sell for $2 or less.
Have you ever found some Dreamcast stuff in a strange location?
