Comscore expects Cyber Monday (that s today!) to surpass $700 Million in online spending, which would make it heaviest online spending day on record.

Comscore bases this prediction on the 17% increase in online spending so far this year's holiday shopping season (November 1st - 23th). More than $9.3 billion has been spent online during the season-to-date according to Comscore.
Additionally online retail spending was strong on both Thanksgiving Day (up 29% to $272 million) and Black Friday (up 22% to $531 million), outpacing the season-to-date growth rate.

The hottest category continues to be video games, consoles & accessories, which is up 134%versus the corresponding days last year. Sales of Nintendo Wii, PlayStation 3, and popular game Halo 3 continue to drive growth in the category. See also this report about the best-selling products on Black Friday.
