Cool. Love hearing about this kind of thing. I don’t think I’m giving away any secret sources (new records after all) my 3 go to discogs sellers with the best prices and good packaging are PopMarket, Record Mule, and Plaid Room. I think I’ve posted about these before.
There is a small independent here in Portland, Clinton Street Records, that also runs a label. I try to support him and buy the stuff he issues. He has lots of good used records too. My favorite here in Portland though is Music Millennium. As I’m certain Greg knows, It’s a pretty special place, and has been for a long time. I spend way too much money in there. One thing I like is that they stay open really late and I can haunt the isles in there for hours. Check it out if you’re ever out this way.
