Spotted this today. Store liquidating its stock, and it just happened to have a crapton of Drill Dozers. It's not a super-valuable game, but could yield some decent profit for someone who wants to invest the time into reselling them (CiB seems to go for ~$10-15 apiece).
I don't have the time to invest in reselling that many copies myself. If anyone here does, go nuts.
