Where do you buy your vinyl?

Just getting in to this hobby and have a small collection some bought from garage sales and more inherited, but I am beginning to understand the immense difference between a great recording and one that is just ok and as I look to build my collection further, I am thinking of buying some new/unused records. I am not looking for collectibles, only for high quality sound and I am interested in where the best places are and how to figure out which pressing to get.

Here are the outlets I know of so far:

Acoustic Sounds    https://store.acousticsounds.com/
In the Groove    https://www.theingroove.com/
popmarket    https://www.popmarket.com
The Sound of Vinyl    https://thesoundofvinyl.us/

Are there other good places to look? How do I distinguish between versions? Do some stores have better quality s.t. I can rely on them to stock the best copies?
