Where I am MDMA is upwards of £40 on the street but the majority of stuff on Agora is like £20-30, with the average probably being about £25. I've tried it and it's good stuff. Probably better than the stuff we have locally.
What's up with the price difference? Are local dealers just greedy?
Cuts out middlemen. That's what your local dealers are, middlemen.
Whereas vendors on the darknet can be the source, or a lot closer to the source at the very least, without endangering said source.
Also: the whole "mail" thing ends up putting everyone on a level playing field: local prices aren't a thing on the DNM since the competition is global.
