The Everything Store: Jeff Bezos and the Age of Amazon

by Brad Stone

Sinegal explained the Costco model to Bezos: it was all about customer loyalty. There are some four thousand products in the average Costco warehouse, including limited-quantity seasonal or trendy products called treasure-hunt items that are spread out around the building. Though the selection of products in individual categories is limited, there are copious quantities of everything there—and it is all dirt cheap. Costco buys in bulk and marks up everything at a standard, across-the-board 14 percent, even when it could charge more. It doesn’t advertise at all, and earns most of its gross profit from the annual membership fees. “The membership fee is a onetime pain, but it’s reinforced every time customers walk in and see forty-seven-inch televisions that are two hundred dollars less than anyplace else,” Sinegal said. “It reinforces the value of the concept. Customers know they will find really cheap stuff at Costco.”
