Costco Wholesale Corporation, commonly called just Costco, is a membership-only chain of warehouse clubs that offer discounted prices on bulk products. This product is based within the United States, but it is a multinational corporation and it is the second-largest retailer after Walmart in the world. In fact, in 2016, it became the largest retailer of certain goods including wine, rotisserie chicken, organic foods, and prime beef. The Costco headquarters are located in Issaquah, Washington. The company employs more than 231,000 people as of 2017; in their warehouse stores, depots, and other businesses. They hire a lot of cashiers, but most of their workforce is involved in the distribution, and supply line section of the business. That includes those positions within the store that receive the items, sort them, and place them on shelves.
