Wal-Mart joins the Thanksgiving rush
Wal-Mart certainly wasn't going to be left in the dust this Thanksgiving.
The world's largest retailer announced Tuesday that it will begin its in-store Black Friday sales at 6 p.m. on Thanksgiving Day, two hours earlier than last year.
In addition, Walmart.com will begin offering Black Friday sales on a limited number of items Thursday morning—likely before the turkey is even in the oven.
"We're always looking at what's going on in the competitive environment," said Duncan Mac Naughton, executive vice president, chief merchandising and marketing officer for Walmart U.S.
The giant retailer will bring back its one-hour guarantee during events at 6 p.m. and 8 p.m. on Thanksgiving, followed by an 8 a.m. event on Black Friday. If customers are in a designated line within an hour of one of these sales' kickoffs, they are guaranteed to receive an item at a certain price either that night or before Christmas.

The program is expanding to 21 products this season from three last year, ranging from a Vizio 60-inch LED HDTV for $688, to a one-carat diamond and sterling silver pendant and earring set for $98. The stores will integrate wristbands so shoppers can browse while waiting for the events to begin.

Wal-Mart is also ramping up its social media and online components, advertising "manager's specials"—when managers will lower prices for an entire category—on its local Facebook pages, and curating deal maps on its website to be viewed while in-store.
"Our goal is to have a lot of folks come shop with us at 6 p.m.," Mac Naughton said.
