Come Thanksgiving, you might want to skip that second slice of pumpkin pie.
Some retailers, including Walmart, will open their doors to Black Friday crowds earlier than ever.
Walmart will launch the first of its Black Friday sales events at 8 p.m. Thanksgiving. That's two hours earlier than last year.
Sears, which opened at 4 a.m. last year, will also open its stores at 8 p.m. Thanksgiving and, like Walmart, stagger Black Friday deals overnight and into Friday.
"It would have to be something pretty awesome for me to go out after Thanksgiving dinner," said shopper Gina Woodley, who confessed she's hit the stores at midnight in years past. "I have to admit, I have done it."
Black Friday shopping encroaching on Thursday is enough to give some holiday traditionalists heartburn.
"I think it should be a day of family, instead of being out shopping," Brenda Cordero said.
But for others, like Esmy Aguilar, the door-busting, bargain-hunting chaos of Black Friday is part of their tradition.
"It's part of the festivities, something we would look forward to doing, part of the fun," Aguilar said.
In advance of the shop-'til-you-drop kickoff, many retailers' ads are leaking earlier than ever to websites dedicated to Black Friday.
Walmart's ad revealed deep discounts on electronics like a $399 iPad which includes a $75 store gift card, as well as a $149 X-Box bundle and $6 sweat shirts and slippers.
