Management has decided to offer discounts when a customer buys more than one of any given item. This discount only applies to the specific item(s) that the customer purchases in volume. For example if a customer buys five sets of cups and one coffee maker, they will only receive a discount on the cups. The discount percentage is based upon the number of items purchased and not the item itself.
