Reuters Wal-Mart cuts prices on food ahead of holidays Tuesday November 21, 3:50 pm ET By Jessica Wohl CHICAGO (Reuters) - Wal-Mart Stores Inc. (NYSE:WMT - News), the largest seller of food in the United States, slashed prices on hundreds of grocery items on Tuesday, putting more pressure on traditional grocers just two days before Thanksgiving. Wal-Mart, the world's largest retailer, has already cut prices on toys, appliances, electronics and apparel to attract more holiday shoppers. Now it is also trimming prices on hundreds of fresh and dry grocery items. The retailer is eager to attract more shoppers this holiday season after back-to-back months of disappointing sales growth in September and October. Wal-Mart has said it expects the markdowns to help improve sales growth. Holiday discounts could be coming in other parts of its stores, but Wal-Mart declined to give details. Wal-Mart said that the price of many food items would be lowered by as much as 20 percent. Some items were discounted more heavily.
