I've never seen a TG16 game at a thrift shop. I have, however, found lots of other games and game systems for good prices. Salvation Army near me has the best prices. Games are $2, systems are usually $10-15. I've picked up a Gameboy Advance, N64, Gamecube and probably 20+ Gamecube, PS2 and XBox titles for super cheap. Goodwill tends to be twice that price and has a worse selection.
