December 26, 2012—With Christmas officially over the latest holiday shopping numbers for online spending are in. According to comScore, shoppers spent nearly $38.7 billion online for the holiday season to-date. This year’s sales are up 16 percent from a year ago thanks to the incredible amount of last minute shopping. Last week’s sales totals were up a massive 53 percent over the same period last year (week ending December 21, 2012).

Free Shipping Day (Monday, Dec. 17) incurred $1.01 billion in online spending compared to the previous year, which totaled a 76 percent growth rate. ComScore chairman Gian Fulgoni said, “We typically do not see such heavy spending this late in the season, but the fact that Free Shipping Day occurred on a Monday, combined with the fact that so many retailers extended their promotions into the middle of the week-with guaranteed shipping by Christmas helped deliver an encouraging late-season surge. The result has been a significant uptick in the season-to-date growth rate, which now stands at 16 percent.”

The top three heaviest days of online shopping this year occurred on a Monday, although the 2012 holiday season saw 12 days with more than $1 billion spending, surpassing last year’s total by 10 days. For 2012, Cyber Monday (Nov.26) was the largest shopping day of this season with a record $1.465 billion in spending followed by Tuesday, Dec. 4 with $1.362 billion and Green Monday (Dec.10) with $1.275 billion.
