Not finding anything at some thrifts didn't deter me. I went to TRU and picked up 14 games for $3 or so apiece. Including DC titles, PSX, even a PS2 title. They may be suck ass titles, but I'm a sucker for $3 games.
A bunch of titles are 70% off- that's how I reached the $3 price point. I couldn't believe they had N64 titles, but nothing worth picking up at a higher price point (for me) and maybe only 5 titles.
I picked up Virtua Tennis GBA (2 copies- should I get more?) for $3 apiece, new. One's for me, the other is for ?? Probably a friend who I pick up crap for.
