NEW YORK -- The doors are open. The sales are here. It's Black Friday.
Black Friday faithful are already scooping up deals at malls and department stores across America.
A few stores -- like Kmart and Radio Shack -- opened Thursday morning, but most -- including Macy's, Best Buy, Target, Kohl's, Toys R Us, J.C. Penney and Sears -- waited until after Thanksgiving dinner was served.
As night fell, Manhattan's bustling Times Square was packed with deal hunters -- some from as far away as Sweden and Florida.
"My God, it's crazy down here!" a mother exclaimed inside Toys R Us as she trailed three children past a robotic Tyrannosaurus Rex. Nearby, a worker wearing an elf hat pumped up the crowd: "I guar-an-TEE it's $24.95!" he crooned.
Walmart, the nation's largest retailer, kicked off its sales at 6 p.m. At the chain's location in Neptune, N.J., shoppers braved long lines in order to secure deeply discounted items.
Lola Stoball had her niece stand in line for a 50" LED TV on sale for $218 while she was waited for an iPad mini. Stoball shops every year on Thanksgiving, and was also planning to hit Target and Toys R Us.
"I just love shopping," she said. "I come because it's fun and for the deals."
But not everything went smoothly across the nation. In fact, the hunt for bargains became a bit of a contact sport overnight.
Police had to pry some shoppers off the floor at a Walmart in Houston after they refused to let go of a discounted TV.
And in Los Angeles police were dispatched to another Walmart after a brawl broke out over a $5 Barbie.
"There was obviously a fight between a guy and a girl over a Barbie doll and the girl. And the girl socked the guy in the face just to get the Barbie," said one witness.
Electronics were among the most sought after sale items at the Walmart, and some shoppers were buying for themselves. Hassan Mehdaoui picked up an Xbox 360 for $99.
"You can't go wrong with that price, it's awesome," Mehdaoui said. "I love getting stuff like this, it's what I live for."
Yet there was some backlash. Some stores, like Costco, have said workers "deserve" Thanksgiving off.
And customers are discovering they don't need to leave home -- or even the dinner table -- to get deals. Many retailers launched their first holiday discounts several days ago across their sites and mobile apps.
The shift to online shopping is showing up in Black Friday sales numbers. Revenue growth is now about half of what it was a decade ago, and foot traffic continues to decline at brick-and-mortar locations.
Retailers hope that online shopping will help fill the gap. The National Retail Federation projected holiday season spending would grow 4.1% more than last year to $616.9 billion. Online spending is expected to grow even faster, with various estimates projecting a spike between 8% and 15%.
Stores are competing against each other to grow their slice of that pie, which is why opening times are getting earlier and earlier. But maybe the joke's on them: A CNNMoney analysis found Thanksgiving openings did little to boost sales.
Still, there is something magnetic about Black Friday. At the Macy's flagship store in Manhattan, Manuel Lizaralda and his sister Stephanie were shopping for shoes, jackets, and sweaters to give their mother as gifts.
Manuel had traveled from Bogota, Colombia to visit Stephanie, who is attending school in New York.
They spent roughly two hours shopping at Macy's, but they weren't finished: They were headed for a nearby store, Zara, to shop for more apparel and shoes. Zara's Black Friday special was 30% off everything.
"It's amazing," Stephanie said. "But it's too many people; it gets annoying."
