Inside A Wal-Mart Stores Inc. Location Ahead Of Black Friday

An employee tags an item for store pickup, a program where customers select and pay for items online for pickup, at a Wal-Mart Stores Inc. location in Chicago, Illinois, U.S., on Wednesday, Nov. 25, 2015. In 2011, several big U.S. retailers moved their opening times to midnight; in 2012, Wal-Mart crossed the Rubicon and opened its stores at 8 p.m. on Thanksgiving Day. But after last year's Thanksgiving weekend retail sales fell 11 percent from the year before while overall holiday sales rose, some retailers have been reconsidering.
