Who sells the most vinyl?

Amazon. Obviously.

But before we move on from the question, it's interesting to note who else sells vinyl in quantities in the US:

1. Amazon 12.3% of US retail vinyl market
2. Urban Outfitters 8.1%
3. Hastings Entertainment 2.8%
4. Hot Topic 2.4%
5. Trans World Entertainment 2.2%

Yes, there's two clothes shops on that list. (I know Hot Topic would claim they're some sort of alternative lifestyle shop, but they're a clothes shop with a record rack.)
