Lowe's workers collect shopping carts in the parking lot at the Lowe's Home Improvement Warehouse in Burbank, California August 15, 2011. Lowe's Cos Inc reported weaker-than-expected quarterly sales and cut its fiscal-year outlook for the second time in three months as homeowners put off big renovations in an anemic U.S. economy. The news pushed the second-largest home improvement chain's shares down 1.3 percent on August 15, 2011. REUTERS/Fred Prouser (UNITED STATES - Tags: BUSINESS EMPLOYMENT)
