Recreational Equipment, Inc, commonly known as REI, is an outdoor recreational retail company whose product offerings include sporting goods, camping gear, and clothing. REI has over 150 retail locations in 35 states, as well as a retail website. While the website offers thousands of products, each retail location carries only a fraction of the total number of items offered by the company online. Explain why a company like REI would choose to offer so many products for sale on its website but only carry a fraction of those products at each of its retail stores, and why the products carried at each retail store may vary from one store to another.
