I've lurked this place for so long but thought it was time to make an account to post in here.
Good
Vitriol Records - Justin, who runs it, is super nice and responds to every email as soon as he can. Only problem is he ships records inside the covers so I almost always get them with a little spine damage.
No Sleep Records - Again, I'll always get a quick reply to enquiries. Recently received an order that, due to rain damage, the record sleeves had stuck together during transit. Since one was a test press and the other was a preorder I asked if they had any spare sleeves. They didn't but Chris offered to sell me two regular LP's for a good price to replace the covers.
Throatruiner Records - Matthias has been such a great dude to deal with and always includes little extras in anything I've bought from there. Ships really quick and everything's packaged safely.
City Of Gold Records - Nice little label, cheap prices/shipping and quick replies to enquiries.
Bad
6131 - Pre-ordered Swamp Thing's "In Shame" LP and something else, never got it, and the replies were always dodgy. Didn't offer to give my money back or anything.
