Since gull has abandoned this thread- I had a similar experience recently. Went to the local retro game store in the next town, and the kid there has a big plastic tub full of Atari commons to sift through for $2 each.
I spied two naked Activision carts, and took a gamble on them- and it was good!
I got Dolphin and Pressure Cooker! Two very good, late-era Activision 2600 games that are fairly rare to find in the wild.
I also picked up a Phoenix, Vanguard, and the rare "Raiders Lost Ark" label variation with the Raiders movie logo in the front instead of the regular text one - all for $2.00 each. He's a bit younger and doesn't study Atari pricing as much as he does NES and Sega pricing, where he charges ridiculous eBay BIN prices for commons.
I also picked up a clean, 100% working Coleco Gemini with both controllers and power supply and 10 games for $50. Not a bad haul.
He also has a Goldstar 3DO I have my eye on.
