Well if you offend vendors and people you can give them gifts by just giving them items for free. It's a mechanic that has been in other Divinity games. I would hope that they will add a tutorial to the selling part for newer players.
Definitely good to know, thanks. I played Divine Divinity a long, long time ago but must have completely forgotten about the barter mechanic because nothing jogged my memory while interacting with a the vendors.
