I've never seen anything for the Lynx in the wild. My Jaguar was from the Goat Store but every game I have for it was from the wild. Everything I have for CD-i and the Atari 5200 came from the wild as well. all my TG-16 stuff too. well I did get one game from ebay.
I agree with bum-man's definition of "the wild" too.
every console listed here:

I did buy a Saturn at a game store but have since found another at a thrift.
