How to Get the Best Deals for Christmas at the Last Minute

With Christmas just days away, many retailers are slashing prices.

"Retailers overstock for the holiday, so you're going to see massive discounts," Hitha Herzog, chief research officer for H-Squared Research, told ABC News. "They just want to get that merchandise out."

Kohls is currently offering an additional 20 percent off orders of $100 or more, and 15 percent off orders under $100, as well as allowing customers to buy their items online and then pick them up in their local store.

At the Gap, all men's and women's clothing that is not already on sale is now slashed 50 percent off.

In addition, Amazon Prime Now's "Procrastinator's Delight" promotion allows anyone in more than 30 metro areas across the country to order goods on Amazon up until 9:45 p.m. on Christmas Eve and receive the items by midnight.

There is also a trick to get even lower prices at many retailers, according to Herzog.

"When you go into a store, and people don't really know this, but you have the option to haggle for that price," Herzog said.
