Wal-Mart ( WMT) is cutting prices on many of the items it sells, from food to TVs and other electronics, by 10% to 30%, the company said Tuesday. The world's biggest retailer said it's focusing its efforts on items customers want to buy at this time of year, such as food and goods for the Super Bowl, fitness items and home products. Thousands of items are affected by the new prices, the company said. Wal-Mart is also offering no interest for 18 months on purchases of $250 or more with a store credit card. "We all know economic times are tough so our plan is to help with added savings throughout the year, focusing especially on what people want, when they need it," John Fleming, chief merchandising officer at Wal-Mart, said in a statement. "Shoppers are depending on us to deliver the best price so they can stick to their plans, no matter what the economy throws at us. We won't let them down."
