Retail sales might have gained momentum in January as promotions enticed U.S. Shoppers. Retailers such as Gap topped the charts for January sales, making it clear that household spending will keep growing. Retail sales might have climbed due to post holiday specials. Retail businesses are learning from these special promotions as a way of improving retailing. Retail jobs may also ride as retail gains ground. Sales at stores at 30 chains tracked by Retail Metrics climbed 4.4 percent in January. Could this be a sign that U.S economy is showing a strong back from the plague of the economic downfall? Maybe.
