Dude read the smokersguide online I'm not sure of the exact address but it's one of the best as far as where to get shit...because there ARE places in Amsterdam that are bullshit...and as soon as they hear your accent they pul out the shitty shit....many true stories about that shit......but that guide tells you some of the best

for Bud got o Dekampring, (NYC Diesal, Amnesia Haze)
or oh fuck i forget ..but there are a couple really good sites
Damn i have a list waiting of all the buds i want to try there and where i can get them but i forget where it is..........
