Wal-Mart Taking on Target in Yet Another Category

Wal-Mart on Tuesday announced a series of initiatives to beef up its health and wellness offerings, at a time when low-price competitor Target also has the segment in its crosshairs. On Saturday, the world's largest retailer will host what it's dubbed "America's Biggest Health Fair," at which it will provide free glucose, blood pressure and vision screenings at more than 4,400 of its U.S. stores. The retailer will also offer shoppers commonly needed seasonal immunizations, including the flu shot, for a fee.
