274. Business Case Problem with Sample Answer Price Discrimination. Dayton Superior Corporation sells its products in interstate commerce to several companies, including Spa Steel Products, Inc. The purchasers often compete directly with each other for customers. For three years, one of Spa Steels customers purchased Dayton Superiors products from two of Spa Steels competitors. According to the customer, Spa Steels prices were always 10 to 15 percent higher for the same products. As a result, Spa Steel lost sales to at least that customer and perhaps others. Spa Steel wants to sue Dayton Superior for price discrimination. Which requirements for such a claim under Section 2 of the Clayton Act does Spa Steel satisfy? What additional facts will it need to prove?
