Black Friday Sales

Black Friday sales got off to an early start on Thanksgiving Day.
Well over 100 million people were expected to shop during the four-day Thanksgiving holiday weekend.
Most of the big retail chains, including Wal-Mart and Target, have increased security in place.
This year marks the five-year anniversary of Black Friday 2008, when a Wal-Mart worker was trampled to death in New York and two men died after shooting each other at a store in California.
