Inside Costco: the magic in the warehouse

Fortune:

Costco is a retailing colossus. Its worldwide sales trail only those of Walmart, which has 11,528 stores to Costco’s 715, and Amazon, which just climbed into second place. Costco is the world’s largest seller of choice and prime beef, organic foods, rotisserie chicken, and wine (!), and it moves more nuts than Planters. Its private label, Kirkland Signature, which sells everything from packaged goods and beverages to apparel, generates more revenues than the Coca-Cola Co.

But Costco, big as it is, prides itself on not being your typical multibillion-dollar company. That is where the culture comes in.

Costco became a phenomenon by doing things its own way. But with Amazon ever more powerful, millennial shoppers burgeoning, and a new generation of leaders awaiting its turn, can the company preserve its edge?

I’m not a big box store fan but this story about Costco was fascinating.
