One simple thing I learned recently is to focus on who presses the release, and one company is qualityrecordpressing.com. There are a few others companies who do great things and some are expanding operations luckily, but QRP pressed the Sabbath, Rush, Miles and Coltrane reissues that sound great and come in quality sleeves.
I try to order from an Indie store close by (Bull Moose in Maine and they ship) fun to talk to people who know before I buy the crud. I have recvd crappy vinyl via Floyd, Hendrix, etc from Big Box, local, poor pressings don't discriminate.
I dig the suggestion of avoid shipping vinyl is summer, I'm making a note of that. Simple science.
