I found one at HEB off Buffallo Speedway on Friday, there were a few more. Not sure if they're still there. If I were you I'd not waste your money though.
Check HEB on Alabama/Dunlavy. HEB Fairfield has gotten Bomb! Bible Belt, Noir, Coffee Noir, Vanilla Noir, and Wine Noir in the past. Kroger on Buffalo spdwy at Westpark sometimes has decent Prairie. Check Spec's to see if any stores still have it in inventory. Austin stores may have some since the release was staggered there.
I actually live a hr south of houston in a very small town..our specs still had most of the only case they have available.
