Cyber Monday came in as the biggest shopping day of the year so far, said John Squire, chief strategy officer of Coremetrics.

The average online order was valued at $194.89, 8.3 percent higher than last year's $180.03 average figure.

Affluent shoppers drove up sales of luxury goods up 24.3 percent over 2009 Cyber Monday.

Consumers this year appear much more willing to open their wallets and are turning to online stores for the convenience of shopping wherever and whenever they like, but also as their primary source of information about products and inventory levels,” Squire added.
