FILE -In this Friday, Nov. 23, 2012, file photo, Black Friday shoppers pour into the Valley River Center mall for the Midnight Madness sale, in Eugene, Ore. U.S. shoppers hit stores and websites at record numbers over the four-day Thanksgiving weekend, according to a survey released by the National Retail Federation on Sunday. They were attracted by retailers' efforts to make shopping easier, including opening stores on Thanksgiving evening, updating mobile shopping applications for smartphones and tablets, and expanding shipping and layaway options.
