Retailers report the peak in online shopping is moving a bit closer to Christmas as express shipping becomes more popular, cheaper and also faster. One of the first peaks is noticed on "Cyber Monday", the day after Thanksgiving.
"You're seeing the difference between the shipping deadlines and the (shopping) peaks come closer and closer to Christmas," said Heather Dougherty, an analyst at Nielsen/Net Ratings.
Market research firm comScore says December 12 or 13 tends to be when most online dollars are spent.
Last year, online shoppers spent $556 million on December 12, compared with $485 million spent on Cyber Monday, which was the ninth-heaviest shopping day. Shoppers spent $305 million online on the Friday after Thanksgiving, comScore said.
