What Is Costco?

We are a membership warehouse club, dedicated to bringing our members the best possible prices on quality, brand-name merchandise. With hundreds of locations worldwide, Costco provides a wide selection of merchandise, plus the convenience of specialty departments and exclusive member services, all designed to make your shopping experience a pleasurable one.

The History of Costco

The company’s first location, opened in 1976 under the Price Club name, was in a converted airplane hangar on Morena Boulevard in San Diego. The company found it could achieve far greater buying power by serving small businesses and a select audience of non-business members. With that, the growth of the warehouse club industry was off and running. In 1983, the first Costco warehouse location opened in Seattle. Costco became the first company to grow from zero to $3 billion in sales in less than six years. When Costco and Price Club merged in 1993 to become PriceCostco, it had 206 locations generating $16 billion in annual sales.

Our operating philosophy has remained simple: Keep costs down and pass the savings on to our members. Our large membership base and tremendous buying power, combined with our never-ending quest for efficiency, result in the lowest possible prices for our members. Since resuming the Costco name in 1997, the company has grown worldwide. During the past fiscal year (ended September 3, 2017), total sales were $126.1 billion.
