Shopping centers' pain continues to be online retail's gain.
In wake of a ShopperTrak report that store traffic posted yet another steep decline last week, comScore has given retailers some hope that shoppers are shifting their spending to the Web, instead of just cutting down on purchases.
The analytics firm on Wednesday said that last week, for the first time ever, online sales eclipsed $1 billion for each of the five individual workdays. The streak contributed to a total online spending increase of 21 percent so far this season, when comparing the days since Thanksgiving to the same period last year.

What's more, comScore said it has seen strong online growth coming from weekend spending, a period that is typically lighter for the Web. In the past, online sales have been stronger during the workweek, when people are in front of their computers for longer periods of time.
"One of the most interesting stories we are seeing this holiday season is the explosion in weekend online spending," said comScore's chairman, Gian Fulgoni. "While we have seen solid growth during the days between Monday and Friday, weekend growth rates have surged to nearly 4 times what we're seeing during the workweeks."
