Gibson Golf Clubs manufactures titanium golf clubs and sells them in retail outlets all over the U.S. and Europe. GGC is revising its current pricing structure. Would the following plans be lawful under federal antitrust laws? Price Plan A: GGC sells Extreme T Clubs to its best customers for $100; however, they will sell the same clubs to other customers for $200. This action will substantially lessen competition. GGS sells Super T Clubs to stores in one market for $150, but will sell the same clubs in stores in a different market for $250. The lower price is charged in the first market in order to match the price that a competitor charges for similar golf clubs in that market.
