Retail stores are closing. You only have to walk by most malls or shopping plazas to see the shuttered Macy’s (NYSE: M) and Sears Holdings‘ (NASDAQ: SHLD) locations. Venture inside the mall and you’ll be greeted by empty storefronts that once housed Radio Shack, Rue 21, The Limited, Wet Seal, BCBG Max Azria, or any of the many other chains that have closed locations or gone out of business entirely.
