Online spending for the first two days of the final shopping rush before Christmas increased 29 percent over the same two days last year, according to comScore.
On Monday, consumers spent US$700 million online, up 33 percent from last year, and they spent another US$670 million on Tuesday, up 25% from last year, comScore said.
For the first 48 days of the season, from November 1 to December 18, shoppers spent nearly US$25 billion online, up 19 percent from the same period last year, and more than shoppers spent online for the entire 2006 holiday season, comScore said.
Although the heaviest online shopping days may be over, consumers will continue to make purchases online to take advantage of last-minute shipping deals offered by some retailers, said comScore Chairman Gian Fulgoni.
Consumers will make purchases online but will pick up their goods at retailers' brick-and-mortar stores, Fulgoni said in the statement.
"It's also clear that many consumers are willing to delay their holiday shopping later in the season this year in an effort to take advantage of any late-season price discounts being offered by retailers," he said.
