Retailers fit better into Places rather than Labels, where they are easily misused.

I'm calling this "exclusively sold at" because I don't believe general retail distribution warrants this kind of data. This is to standardize the way that store exclusive releases are handled, because stores usually don't go in either the release label or the distributor relationship.

I'm not sure how to handle chain stores, maybe a chain is a Place Series, or a chain is the Place "parent" of the specific store?
