Merchandise sales for professional sports leagues is a multibillion-dollar business, and leagues such as the NBA, the WNBA, the NWSL, NFL, and MLB have strict licensing rules for official league merchandise. Suppose you are a huge basketball fan and wish to purchase an authentic pro jersey in large. Go to the NBA Store's Website at store.nba.com or the WNBA website at wn- bastore.nba.com and click on "Jerseys." Select a team and then click on "Authentic" and find the price of the jerseys. Do the same for two other teams. Would the jerseys you found be considered perfect substitutes or just substitutes? Why? Do you think there are other products available that would be considered substitute products for the authentic jerseys you looked up? Briefly explain.
