I pay between $200 - $220 per oz. Some of my most recent strains:
OG Kush, Gelato, Berry Goo, Cookie Monster, Jager OG, Blue Dream, Headband, Gorilla Glue and Creampie.
Also, I frequently pick up "shake" from the strains listed above (and similar) for $100 / oz. I am not taking about "shake" from whole plant processing, but "shake" from storage by distributors - so it is good bud - but mixed and not as pretty or marketable. I like it just fine when I do not have a particular "need" - since I am never sure of its exact makeup, though I know its basic contributors.
EDIT: Oh, I never buy less than an oz at a time, and I usually buy a larger amount - and my prices are based on that kind of regular volume - plus family generosity. If I were to buy by the 1/4 oz, I estimate I would have to pay about $75 - $85 (again family hospitality helps).
