barter with
To swap or trade items with another person, rather than exchanging money. I bartered with some guy at the flea market for a futon, so now I have a place to sleep, at least. I don't have any cash right now—will you barter with me?
barter with someone
to enter into trading with someone without using money; to bargain with someone. Are you willing to barter with me, or is this strictly a cash transaction?
