Growers gotta cover their costs my friend. I live in an illegal state and topshelf is $320 for a 28g bag. My dealer is pretty cool and lets me mix strains in 1/4's or 1/2's and still gives the oz price. Cheapest Oz. I ever got at a CO disp. was Chemdawg for $125 (in Trinidad - generally not a town to buy in because they're raking in the $ off of out of state buyers that don't want to travel farther). For Canna tourism in CO I strongly recommend buying in Bolder, better deals than I've found in Denver and much more pleasant service. And Boulder is on the way to RNP so there is always tourist type fun to be had.
