Thank you for your response Dawn, I would say that when we Buy, we make a purchase that nobody really wants, or wanting to make an offer, when we Sell, it is up for Market, but i really think when we get that type of training on anything, we meet clients who really are looking for something to buy, if we done the math, we may come to those situations that trading deals are less common, becouse marketing are useally Brand new, and of course buy, is something you already have compared to negotiations, talk to that customer about what is agreed, each time we do sales with our customers they are able to find something their looking for.
