Free shipping wars: Retailers ramp up battle for online customers

The move comes less than two months after Walmart started offering free two-day shipping on eligible orders of at least $35. CBS News financial contributor Mellody Hobson joins "CBS This Morning" from Chicago to discuss the retailers' goals.
