selection and quality are quite variable ...
As businesses tend to "diversify their revenue streams", many gas stations, liquor stores and a few grocery stores (at least in this area) have little humis of this sort ... first I saw was in a Standard station ... theirs was a pretty nice humidor (wood w/glass window) but their selection was pathetic and they were obviously neglected ... attendant told me "the guy who takes care of that" hadn't been around for a couple of months ...
Surprisingly, some of them have a moderately decent selection that looks as if it's being cared for ... some have prices that are fairly reasonable, some have prices that even by CALIF standards are off the charts ...
