Well me my system is i have about 5 or 6 ppl i kno who sell, so i just call each one until i find some, or before i had that system i really remeber almost going insane because i was on the street asking ppl for about a week and then coudlent find any, ( wha i reccomend is to meet some hookers , they usualy get high alot off coke and shit and they can usually get you some bud to and get you into that circle, worked very well for me )
