Yes, you can , but most is audiophile stuff and the range is limited. If you pick up a copy of record collector mag there are plenty of adverts for suppliers, I have used Audiophile International and a couple of others I cant remember.
The good news is that they supply used vinyl, its all given a thorough check and graded for condition. These conditions are not overstated, if its sais mint, thats what it means. They are sent in a strong card board package, Ive bought loads.
