Yeah I just realized one of my survivors has the tough negotiation hero bonus so that's part of the reason I'm swimming in influence after I sell all my useless stuff.So... Business plus Tough Negotiation plus Satellite Broadcast equals 825 influence selling a Case of Bulk Plague Cure. 500 from the trader and 325 from the air.
I love how selling a post it note that says 'call mom' gets me 17 influence. Or I sell cases of bad ammunition for influence. I guess one mans junk is another mans treasure.
