140 Chapter 5 | Mathematics of Merchandising 5 MATHEMATICS OF MERCHANDISING Have you ever wondered why prices of items sold at wholesalers like ‘Costco’ and ‘Wal-Mart’ are cheaper than prices of the same items sold at a convenience store; why prices of items are cheaper online than at retail outlets; or how a ‘Dollar Store’ manages to sell items for a very cheap price? Large distributors buy directly from manufacturers to reduce the cost of the product offered to consumers. Online stores have less overhead expenses, employee time, storage costs, etc., which enable them to pass on the savings to customers. Although stores like the ‘Dollar Store’ make small profits on each item sold, they make high overall profits by selling large quantities of items. Pricing responsibilities such as these, and many more, lie in the hands of a seasoned merchandiser.
