Costco Wholesale opened its first store in Seattle, Washington in 1983. Founders Jeff Brotman and Jim Sinegal had a simple yet powerful idea: allow people to save on basic necessities and consumer staples while taking advantage of special offers on high-end luxury items and durable goods. With $71 billion in sales and more than $1 billion in net income for their latest fiscal year, Costco is the leading player in the warehouse club segment of the discount retail industry, the fifth largest retailer in North America and ninth in the world.�

Given this context as well as competitive pressures, Costco has managed to retain its leading position because
