I am lucky enough to live in an area that has a weekly flea market where I can dig for 3-4 hours every Saturday morning. This seems to be the last good place to find those true deals. As far as jazz, just this year I've found VG/VG+ first pressings of Kenny Dorham's Una Mas, Chet Baker Sings and It Could Happen to You all for $1, along with a lot of Coltrane, some Miles and some other 60s BN titles. For most other stuff, I come across classic titles/artist all the time for $1-3 that are worth $20-50, or sometimes even more, in a shop. This is where I get most of my enjoyment vinyl "shopping" these days aside from the occasional eBay find.
