So if it's been said, sorry.
You shouldn't be able to sell drugs such as stimpacks, psycho or mentats to a man selling clothes/armor.
The same for the rest of the items. This might make it a more immersive economy.
And some people just simply will not barter with you, so you have to spend caps.
An arms dealer with limited stock might want some ammo for the guns that he's selling, such as .44 magnum rounds, but he don't have any need for microfusion cells and will not accept them.
A wealthy settlement's arms dealer will not accept crappy weapons with low CND or just simply bad weapons overall such as chinese pistol.
But even if you have 50 combat shotguns and someone is willing to barter you for them he will not give you his whole shop for all of them. A limit of 1 - 4 weapons per week.
This would mean you cannot spam-sell laser rifles or plasma rifles to everyone and gain a massive amount of money.
But maybe this is too much for the current engine, should I double post this in fallout 4 suggestions...`?
It is not much for the current engine, since it handles that in Oblivion. But, the world of Fallout is a world of scavengers, not established economies. Trading what you have and accepting a variety of things makes more sense in the Fallout environment than specialized vendors.
