Q: Reserve Supply Corp., a cooperative of 379 lumber dealers, charged that Owens-Corning Fiberglass Corp. violated the Robinson-Patman Act by selling at lower prices to Reserve's competitors. OwensCorning had granted lower prices to a number of Reserve's competitors to meet, but not beat, the prices of other insulation manufacturers. Is Owens-Corning in violation of the Robinson-Patman Act?
