Customers purchasing appliances can purchase a three-year service contract that provides free repair service and parts. When a customer needs Sears’ appliance repair service they call for an appointment that make take up to two weeks. The repairman arrives and diagnoses the problem. If the repair requires a new part, the repairman will replace it if he is carrying it on his truck. If he doesn’t have the part on hand, he must order it. If the part is not in stock at Sears, it is ordered and sent to the customer. After the part arrives, the customer must make another appointment to have the repair technician replace the part. It make take two weeks to schedule the first repair visit, another two weeks to order and receive the part, and another week to schedule a second repair visit after the part has been received. 1.
