PARAMUS - Retailers across the country are gearing up for the start of the holiday shopping season, which will start as early as Thanksgiving Day this year.

Black Friday is often the day retailers begin to get out of the red and turn a profit.

The big deals aren't here yet, but shoppers are already hitting stores ahead of the crowds. Some will have barely digested their turkey before heading out on Thanksgiving.

Wal-Mart starts its doorbuster deals at 6 p.m. Thanksgiving night, with two more waves of deals into Friday morning. And for certain items, if they don't have them in stock, you're guaranteed to get it by Christmas.

"Last year, we launched our one-hour guarantee with 3 items," says Wal-Mart spokesperson Danit Marquardt. "We're bringing it back this year with 21 items."

Best Buy is also opening doors at 6 p.m. Thursday. Toys R Us starts doorbuster deals at 5 p.m.

Shopper Melissa Collazo believes the best deals are to be had on Black Friday for shoppers who can get there early. "By the afternoon, nothing is left," she says. "Everyone is here in the morning."

Others say they want to stay as far away from the stores as possible. "I'm not really interested in being out and fighting the crowds," Rob Carcione says.

Many say they will shop online, and from the comfort of home.

Stores say they will have extra staff and security on hand to control the crowds.
