Create a plan to keep a customer who constantly asks for discounts on all of his purchases.

You are a salesperson at a local building supply store. For the past five years, you have dealt with a contractor who constantly asks for discounts on all of his purchases. You have consistently given him discounts in part because this contractor is one of your stores biggest accounts year after year. You are informed that you can no longer provide these “special” discounts to this customer. Create a plan to keep this customer’s business.
