Online Vinyl Stores that don't OVERGRADE!

Almost all records that were sealed when I bought them had some kind of warp. So, I don't believe that being sealed for 40–50 years could “guarantee” anything. That's why I'm usually avoiding sealed records, and even if I would ever buy it, I'd never overpaid for the fact that it sealed.
Besides, I typically prefer UK and other foreign pressings to US ones, and they were rarely sealed even back then, when they were new.

 

You make some good points. I guess no matter the choice made their will always be risk involved.
