Sam Walton founded both Wal-Mart and Sams Club to provide customers with good quality products at cheap prices. Wal-Mart has grown slowly while offering a wide range of goods, and Sams Club has expanded more rapidly focusing on selling bulk quantities. While Wal-Mart stock dropped 6.6% last year and revenue was $348 million in 2007, both companies have largely succeeded in their business endeavors competing against stores like Costco.
