Hi El Maco!
I'm very interested also.
I don't know many growshops but i have seen in Prins Hendrikkade 10 /11 near of central station and in Haalemmerplein.
I don't know nothing about prices.
Wishes.
Hello friends could help me?
What better growshop in amsterdam, which has the best prices and products?
If you have one near the center (dam) or near the place of cannabiscup would be great.
thank you
EL MACO
