Coremetrics released data revealing that online holiday shopping traffic peaked on November 28th, the Monday after Thanksgiving.

Traffic on Mondays was 16 percent higher than the average day for the three weeks prior to the Christmas holiday -- November 28th through December 18th.

"Data revealing spikes in online activity on Mondays this holiday season also signifies a pattern in consumer behavior of 'window shopping' offline during the weekend and purchasing the week day following," says Joe Davis, president and CEO, Coremetrics.
