I don't endorse D&M Liquors because one of the managers has been spotted "flipping" bottles outside the realm of legal retail. That's an abuse of their liquor license, and isn't legal as I understand it.
What that means to you, the enthusiast, is that you can't walk in and buy rare bottles as easily as you should be able to. Instead, they never hit the shelf, and are sold by the store workers on the "grey market" at an obscene markup.
