Store design is key: Fresh food is always placed in the back, which means customers must wind through the entire warehouse to get to them. Costco's main drag is known as "The Race Track," which is designed to expose shoppers to every category of product Costco carries as they make their way through the store, ensuring no one leaves without seeing furniture, electronics, clothing, jewelry, alcohol, food and everything else the store carries.
Costco is one of the world's biggest purveyors of meat, selling $4.5 billion worth of it a year. It sells an additional $4 billion in produce annually. [Source: CNBC]
