Chuck, I agree with what you say, but I have always been puzzled by the low prices in VA and NH. (For bourbon, at least. Scotch tends to be a little more expensive in VA than DC, but you also don't have to pay DC's 9% alcohol tax in VA.)
What do you think explains the lower prices? Are they simply a reflection of bulk discounts the state ABCs receive because of the size of the market they command as distibutors for an entire state? For some reason I had thought VA's proximity to KY might have something to do with it (not just lower shipping costs, but also perhaps closer relationships making for better prices or something.) But that wouldn't explain the low prices in NH.
