Walmart

Walmart makes money by buying products in massive amounts at low prices and selling them to families for a small profit. They give people a one-stop-shop where they can buy everything from milk to tires. They won by building a giant system of trucks and warehouses that keeps their shelves full and prices low. Their secret is their size; they are so big that they can force suppliers to give them the lowest prices in the world. They use Capital Leverage to run a Supermarket model through thousands of giant stores.
