What's the best and cheapest way to get atari commons. I use to run around and buy them for a buck each but the piles have dried up mainly due to me and my buddy buying everyone we have seen. Then I moved to buying lots but now with 200+ 2600 carts I'll end up with 15 new games and maybe some label variations and a big pile for the doubles shelf. Some how out of this I've failed to pick up haunted house and a few other real common things. I've missing like 6 out of the cx1 to 100 and most of them are commons. I hate to pay 5$ a pop for them thanks to shipping and I've done some trading commons for commons. So the question is how does everyone else get there atari commons?
