What is a indirect competitor of Walmart's?

CompetitionIn North America, Wal-Mart's primary competition includes department stores like Kmart, Target, ShopKo and Meijer, Canada's Zellers, The Real Canadian Superstore and Giant Tiger, and Mexico's Comercial Mexicana and Soriana. Competitors of Wal-Mart's Sam's Club division are Costco, and the smaller BJ's Wholesale Club chain operating mainly in the eastern US. Wal-Mart's move into the grocery business in the late 1990s also set it against major supermarket chains in both the United States and Canada. Several smaller retailers, primarily dollar stores, such as Family Dollar and Dollar General, have been able to find a small niche market and compete successfully against Wal-Mart for home consumer sales
