There is a perk that adds +2 charisma when talking to traders.I don't remember the name.
Thanks for all the hints and such ..BUT trading and hunting around unsecure pvp areas like gecro , reno doesn't look a good idea (at least @LVL1)It was even pain in the ass to lvl up my char and make money in guarded areas although i had support char but i was playing solo which was not a good idea IMO.I think everyone should be part of a player faction and socialize with other players. otherwise FO becomes unplayable for most of us.. i guessi will try to find a friendly faction after i lvl up for a little.
