Or... You can do like I do.. After Fort Joy I sell only to a merchant that doesn't sell anything that you need, like the fish merchant at the market in Driftwood. I usually give him a few things to boost his attitude toward me and I get better price for things I sell to him. With 100 points on his attitude toward me and 1 barter point I'm getting 22% more.
In Fort Joy food and drink changes the attitude of the merchants toward you quite a bit.
