I highly recommend checking out a company called Button Shy Games, as they make wallet games (18 card games in a little wallet) that have varying levels of complexity and expansions, but the base games all start at $12 and they release a new one every month. Personal favorites of mine are Sprawopolis (and the other opolis games), Skulls of Sedlec, Wonder Tales, Tussie Mussie, and Revolver Noir for lower complexity games. I can't guarantee all those are in stock though. If you want to do a print and play, In Vino Morte will never steer you wrong.
