Essentially, where I live has two options for game stores: Gamestop, and a local store. The local store occasionally has really good deals, and this is just crap Ive picked up over the last few weeks:

Sega CD - $1
Atari 7800 w/ All Hookups +42 games - $10
Coleco Gemini - $2
Phantasy Star II - $15

The 42 games were mostly 1-3 in the rarity scale. Only exceptions were BMX Airmasters (sadly the TNT version) and Motor Psycho.
