Every time i try to buy weapons from vendors i get info "your offer insults me" no matter how much i am willing to pay.
Was just wondering what was the vendors attitude towards you character buying the weapons?
I was trying to buy a weapon from a vendor and got the same response. I noticed that the vendor had a negative attitude toward the character. So I kept adding gold to till I was able to buy the weapon but, it cost me 100's more gold then what the vendor was asking me for it.
So now I save the game before I try adding gold. Add gold till I figure out what they will take for the weapon. Then reload the save and offer that much to not increase the negative attitude with that vendor.
