Statistics from the National Retail Foundation show the retail industry sales growing at 4% from 2010 levels, led by a better-than-expected holiday season and strong sales growth. The data show that retailers who are able to grow volumes by ensuring footfall, cutting costs and warding off competition will have the competitive advantage. Moreover, with 2010 ending on strong comparable store sales for most retailers, the stage is set for growth in 2011.
