With just hours left before Christmas, many shoppers were still crossing gifts off their holiday list.

"We are last minute shoppers every year," said Idette Anguiano. "Every year."
Nearly 9 million people nationwide take full advantage of the Christmas Eve shopping rush.
"We do this holiday tradition every year where we go out on Christmas Eve and we shop," said Mae Branch.
Stores add extra hours to give those shoppers just enough time. Some look for last-minute stocking stuffers, or an item their little ones have been eyeing.
"Whatever they want, we are going to get them," said Dustin Sater of his children.
Others are still rushing to get the perfect gift that their significant other probably thought they bought days ago.
The mild weather made a typically frantic day of buying much more pleasant.
"We are walking everywhere, it is awesome," Sater said.
But no matter what you're buying, shoppers are spending more this holiday season than they have in years.
The National Retail Federation estimates the average American will spend more than $1,000 on gifts this holidy season.

Mary Ann McGrath, a professor of marketing at Loyola University Chicago's Quinlan School of Business, said the holiday shopping trends are strong.
"Probably the best we have had so far because the economy is doing well and people feel good about their situation," she said.
Not everyone waits until the last minute to buy gifts, however. Experts say 39% of people start their holiday shopping in November, while 56% buy their last gifts in the week leading up to Christmas.
Most stores that are open Christmas Eve will stay open until 6 p.m. or 7 p.m. to help accommodate those last-minute shoppers.
