My Dad dickered. He traded cars and trucks often. was common to take a full day just to buy a car. He always bragged of his trades. He got some very good deals. I got one good deal but I only bought one new truck in my life. I never dickered. Selling a person a two year old mower as a new one is as bad as selling the year before snowblowers that have been powerwashed at Lowes. Not to mention the powerwasher they used and put back in the box.
