Shoppers run through the doors of a Walmart store in Oakland
Shoppers run through the doors of a Walmart store in Oakland, California, November 28, 2008. Shoppers turned up early for holiday sales at U.S. stores on Friday, but the annual pilgrimage appeared thinner this year and many consumers vowed to keep spending down due to a shrinking economy.
