here in SF shops run a delivery service exactly like Mr. niceguy. you dont need a card, just the number. a bike messenger delivers it, and its $40, $50, and $60 eighters. And $70, $90, and $110 quarters.
Its basically like a mobile shop that comes to you complete with 10-20 types of bud, and all the hash oils/waxes, edibles, and keef you could want. Its a pretty darn good deal IMO.
Im cool with the current prices. I smoke darn near every day(only a toke or two, except when skiing when it is much more) and an eighter lasts me around 6 weeks. Good weed should be enjoyed like a fine red wine. therefore it should be priced similarly.
