I've got a lot of stuff I want to sell, but the only Vendor I know of is at Abernathy Farms, and she has poor stock and low caps. Is there a vendor I can find with better stock and more caps near Sanctuary, or is Diamond City my only option? Also, I would prefer someone who isn't a traveling merchant, as whether they're at a location at any given time is random, and I want someone I can use on demand. Oh, and I don't have the ranks in Local Leader to build shops at a settlement, and probably won't for quite a while, so that's out, as well.

Not that I've found

Alright. Thanks. Guess I'll have to charge down to Diamond City one of these days so I can offload loot at decent vendors. Thanks.

Penny's store in Covenant is closer than Diamond City. And she's always smiling, in a Stepford sort of way.

there is the small rest stop diner (forget the name) just south of concord, and if you settle the dispute peacefully then there are two traders there full time, as well as the possibility of a caravan.
