Window shoppers look at a Walgreens storefront Monday, June 26, 2006, in San Francisco. Walgreen Co., the nation’s largest drugstore chain by revenue, said Monday its third-quarter profit rose a better-than-expected 14 percent as sales benefited from a stepped-up expansion pace. The company opened 112 new stores in the quarter, versus 87 new stores in the year-ago period. It said it is on track to reach its goal of opening about 475 new stores in fiscal 2006, which ends in August, and plans 500 store openings in fiscal 2007. (AP Photo/Ben Margot)
