Read the following exchange. What does the woman suggest?

“Man: Up to now, we’ve always offered you a discounted rate of 2% as the favorite customer, but, as you know, what with the price of fuel having risen by 10% in the last six months, our transport costs have risen dramatically.



Woman: I see. Well, what did you have in mind?



M: We were thinking of increasing the rate to 5%, which would only bring it in line with what we charge other customers.



W: I understand your position but that’s still a big increase, especially since we are one of your biggest clients. If we ordered in bulk, which would mean fewer deliveries, would you be prepared to reconsider that rate? To, let’s say, 3%? You’d gain because you wouldn’t have to deliver so often.



M: You mean you’d be buying in larger quantities and therefore paying us upfront for that?



W: Exactly.”
