I second Dusty Groove. I have bought a lot both new and used LPs and have been pleased with my purchases. Very fast shipping. Their grading of used LPs is very fair. I also have had good luck with Music Direct and Acoustic Sounds (only bought new vinyl).
Your favorite place to order new vinyl.
Where is your favorite place to order newly released vinyl. The 180g releases and such. Amazon seems to now be charging above list on some releases. I sometimes order from Music Direct but I am looking for other options.
