As far as I know price discussion is only allowed in NSADD and it's just for personal amounts. So if you want to know what a MDMA pill is going for or a bag of weed it's okay in only that sub forum at the moment.
Tronica brought up linking something like this to BL. StreetRx but I think it is only for US idk.
I briefly saw a blue/white capsule (that is a beacon of ours) briefly before page loaded.
Be safe, please.
