The holiday shopping season is officially over. But it's never too early for retailers to plan ahead for 2008. According to this MediaPost article, the final online holiday shopping numbers are in. comScore, Inc. reported that online shopping for the 2007 holiday season totaled $29.2 billion, a 19 percent increase from the same period in 2006. The heaviest day for online shopping was Monday, December 10, with $881 million in sales. Tuesday, December 11 wasn't too far behind with $819 million. "Cyber Monday," which is usually the day online shopping kicks off following Thanksgiving, came in as the ninth heaviest day.

The best-selling categories included video games, consoles and accessories, which experienced a 129 percent increase from the 2006 holiday season. Furniture, appliances and equipment jumped about 67 percent from the previous season, while sales in the jewelry industry declined marginally thanks to the rising cost of precious metals.
