It makes sense, though. Why would they give the highly coveted flagship product to store that don't support the rest of the product line?
For what it's worth, they don't have to buy just Rain Vodka (which as far as vodkas go, ain't bad). I think it can be anything under the Sazerac/BT umbrella. A local store owner told me that they pushed several bottles of the BTEC on him so he could get an allocation.
