I'll give you my full address, BKA-Friend.
6€ Park weed is really dry and grounded that'd be said.
You can barely smoke that. Been there, done that.
Now, the nicely grown weed surely may go for 6€. But that just for batches since it's not nice for some random stoner to let people into his flat for buying weedslmoa.
The 15€-20€ are the T*rks selling it since they had to buy it off of him for 6.
