Jorge’s Appliance Corp. was a new retail seller of appliances in Sunrise City. Because of its innovative sales techniques and financing, Jorge’s caused the appliance department of No-Glow Department Store, a large chain store with a great deal of buying power, to lose a substantial amount of sales. No-Glow told a number of appliance manufacturers from whom it made large-volume purchases that if they continued to sell to Jorge’s, No-Glow would stop buying from them. The manufacturers immediately stopped selling appliances to Jorge’s. Jorge’s filed a suit against No-Glow and the manufacturers, claiming that their actions constituted an antitrust violation. No-Glow and the manufacturers were able to prove that Jorge’s was a small retailer with a small market share. They claimed that because the relevant market was not substantially affected, they were not guilty of restraint of trade. Discuss fully whether there was an antitrust violation.
