Stopped in to TRU today and saw a flier for a one day sale, today, 12/18. The SEGA Genesis Classic Game Console and Atari Flashback 4 were both discounted to $29.99, down from the $49.99 usual price. Sale price is not available online, but here they are, for the curious:
Do a little research on these before buying. It seems like casual gamers won't find too many faults, but if you're expecting a 1:1 reproduction of these classic games/consoles, you'll probably be disappointed. Hardcore collectors probably want to stick with the original Genesis and games.
