Verjus in DFW, where to buy?

[intence]

I'm looking for Verjus in the DFW area, but haven't been able to find anything locally. Does anyone know of local stores that sell it, and if so, what section to find it in? I tried the Central Market in Southlake, but didn't have much luck, and the salesperson while helpful had no clue either.

Thanks in Advance!
