Apple Stores Perform 17 Times Better Than US Retail Average

New sales data from brick-and-mortar retail outlets reveals that Apple Stores see some 17 times more sales than the national average and lead all U.S. retail chains in sales per square foot. Market analytics firm Asymco, drawing from raw data provided by RetailSails, notes that Apple Stores worldwide smashed the average sales numbers posted by other U.S. chains, raking in $5,626 per square foot in the four quarters ending in August 2011. Apple's performance nearly doubled that of first runner up Tiffany & Co. and was seven times more efficient than the median of the top 20 retailers.
