Hi, since i'm currently trying to find out which Bulk Orders count towards the Barter Guild (for getting BPs), i thought why not make a list here?
These are the ones i found so far:
Repeatable-Scout Leader in Tent outside Junktown (Seem to do not count for BG):

-Hatter in Tent NE in Junktown (Should count, but likely not all):
8x any Hat/Helmet
