Gorgeous, Inc. is a major supplier of dyes, bleaches, gels and other chemical products used in hair salons. Gorgeous just acquired a subsidiary that makes small electrical products, like dryers and curling irons. Gorgeous now refuses to sell its chemical products to any salon or business that does not also buy its electrical products. Dryers and irons of equal quality are available at lower costs from other manufacturers. The condition that salons must buy one product from Gorgeous in order to buy another is an example of a ________________arrangement.

Horizontal price fixing

Vertical price fixing

Tying

Reciprocal dealing
