Minnesota Manufacturing makes a component called Upper B2040. This component is manufactured only when ordered by a customer, so Mississippi keeps no inventory of Upper B2040. The list price is $114 per unit, but customers who place "large" orders receive a 14% discount on price. The customers are manufacturing firms. Currently, the salespeople decide whether an order is large enough to qualify for the discount. When the product is finished, it is packed in cases of 10. If the component needs to be exchanged or repaired, customers can come back within 14 days for free exchange or repair.

information about Minnesota's five biggest customers follows:

All customers except E ordered units in the same order size. Customer E's order quantity varied, so E got a discount part of the time but not all the time.
