Thrift stores rock.
Live has been mentioned before, you get a mixed bag. They usually price everything that "seems" to be (in their weird world) similar about similar prices. And anything that (in their weird world) they think is collectible they overprice (becuase it's really not that collectible.
So about 75% of the stuff is overpriced. I mean seriously, About 25% is actually more expensive used and it godawful condition than you could buy it new at wal-mart.
About 15% is priced what it should be, presuming you actually want it.
Buuut in the remaining 10% you can often find some amazing deals because they don't know that this "similar" item is actaully the rare gem, or that something is actually very collectible.
Some of my finds:
Panasonic 3DO FZ-1 with controller and powercord for 5$ (during a 50% off sale), and 4 crappy games for 80c each.
Sega PICO system in box with all supplies and extra 4 boxed complete games stashed in the PICO box for 7.50.
Sega Genesis 2 and CD2 with both power adapters and two controllers and both manuals for 10$.
Blue Justifier guns for 1.49 each.
Virtual Boy Controller for $1
Sonic Spinball for 69c
Tomcat alley CD for 1.49
Sonic CD for 1.99
MK CD for 60c
Sewer Shark CD for 60c
Ground Zero Texas CD for 60c
I would say 10$ is not a good deal for the barebones genesis (unless you go on half-off day). They don't even sell for 5$ well on ebay unless you have all the necessories. The going e-bay price for a complete gen+CD system is only like 30$. It's sad considering how much we paid for them oriignally.
