Too many people are talking about cannabis being a commodity where people buy based on price alone. You have to look at weed the same way we treat bourbon, scotch, rum, tekillya, and vodka. You can buy a bottle of vodka for a few bucks or you can spend over $1 million/bottle, believe it or not.
I can't imagine 1 oz of bargain basement cannabis costing less than $40 per oz. By the same token (pun intented), there will be certified, organic, tested, well manicured bud for $400 per oz. Some people only want the best and won't care about the price difference.
