Mescal, finding prices....

We fell in love with Mescal while in Mexico recently.

This guy explains why -> see MescalPHD

In any event, we'll be back there soon.  And when we go I want to figure out prices for bottles of certain Mescals when bought in Mexico as opposed to buying them here in Austin.

I can find local prices online, but I cannot find prices for Puerto Vallarta liquor stores online - at least not ones that show Mescal.

I'm good at searching on the internet.  But I can't find this.  Any ideas?
