ive used a couple of delivery services and the prices werent too bad. the alohahealinghouse.com sells it by the ounce but when you buy 65 dollar medicine he cuts it down to 50 bucks an 8th. they had some really good hash also for 40 a gram. they also deliver 24 hours a day seven days a week so that is very convienent. i know that they are thinking of opening a co op in diamond bar because i talked to one of the girls who worked at the pomona co op at a bar and she said after they got raided that they were looking into diamond bar. the city of diamond bar has put a 60 day ban on co ops for the time being, i read this in one of the city council transcripts. a co op is where you pick up medical marijuana and diamond bar is a city. hope some of this helps you sameer. i live in chino which is near you so i hope a IE co op opens too. but seriously try the delivery. i got a free brownie my first delivery.
