Wal-Mart plans to crush competition more than usual

Part of the Wal-Mart (WMT) legacy is that it moves into regions with its huge stores and uses low pricing to push local retailers out of the market. This may give consumers more buying power, but it has caused many local communities to resent the effects of Wal-Mart on mom-and-pop stores.

Wal-Mart now plans to go from hurting sales at smaller stores to hurting sales at its more direct rivals.In an exclusive interview, the company's CEO Mike Duke told The Wall Street Journal that he plans to slow gross margin growth. This means that the world's largest retailer is giving its stores the green light to cut prices on merchandise below their current "everyday low prices."
