I kinda depends on what you're looking for. I like a lot of oddball lounge/exotica type stuff, and there's still plenty of that out in the wild. In the past couple of weeks, I found two really good jazz LPs at thrift stores, which is very uncommon. I found a near mint copy of "John Handy Recorded Live at the Monterey Jazz Festival" (1966) and a really nice 2-LP collection of the Thad Jones-Mel Lewis Big Band on Blue Note/United Artists. On a related note, when traveling in other countries, I find thrift/charity stores especially fascinating. When I was in Quebec City last summer, I spent an entire day hitting every thrift store in the city.
