Sorry for taking so long to reply, I havent been on the board in a few days.
Not really, but a year or 2 ago someone opened a shop called Armageddon in Providence, on I think Broad Street. They have LOTS of cool stuff including new and used vinyl. Check them out for sure!
Sam's Records, Tapes & Stuff used to rule back in the 80's, but he's more into what sells these days and has phased out most of the metal.
That fucking guy used to have seperate title cards for each metal band! He had tons of vinyl, including bootlegs, rare pressings, etc. It was heaven!
