Based upon past performance when it delivers the product late, 75% of customers are willing to accept late orders, while the remaining customers return the product or refuse the order. Customers pay for the shipping and if products are late the shipper waives their fee; however, it cost the company $25 to restock refused and returned orders, and a 20% late penalty for accepted late orders. Refused and returned orders are then returned to stock. The company has calculated its inventory carrying rate is 28%. The business is considering switching delivery companies.
