I love thrift stores. As a collector, I'm grabbing everything I can now (even if I don't want it) for my collection and trade bait. Video game collecting is a hot trend right now, I'm proof of that. While I have been playing games for as long as I can remember (my first video game memory is TI Invaders for TI-99/4A) I just started collecting last summer. More sooner than later people will find out about these places making it near impossible to find anything. I'd suggest to grab what you can now before it all dries up.
If I'd post what I got in the last month I'd be here for a while, so I'll just give a quick summary of my usual thrift store finds. About 90 percent of my Genesis games I found at thrift stores, 99 cents each. Best find from there would have to be Streets of Rage 3.
Both my snes came from thrifts as well.
One is extremely dirty but it still works great. I know someone with a broken power port on his, so i'm trying to trade boards with him and solder on a new one. It was only $3 anyways. The other was $13, clean as new, and came with a bunch of 64 stuff, like power cords and controllers, to boot!
My best find so far would have to be a
boxed Little Samson for $10. The last two CIB ones on eBay sold for $175 and
$130, respectively. A loose cart only usually goes for around $60.
