Rocketski has been in business for several years, and had acquired approximately a 5 percent share of the downhill ski market. During the seventh and eighth years in business, because of a design innovation, its sales increased to the point that it could not meet demand. At about the same time, Rocketski introduced a line of ski bindings that has not been very successful. Rocketski made a slight modification to its ski so that its own bindings are the only ones that can be used without having to use a special adapter plate. Rocketski then began selling all of its skis as ski/binding packages. Some of the dealers objected, but went ahead and purchased from Rocketski because of the popularity of the product and because the package was reasonably priced. Most retailers are able to sell most of the packages to customers, but some customers who want Rocketskis wand different bindings. Discuss the antitrust implications of these actions.
