The U.S. saw its heaviest week in online shopping ever, with consumers spending $6.3 billion in the week ended Dec. 18, up 14 percent from a year ago.

Market research firm comScore said that e-commerce spending to date for the first 48 days of the holiday season hit $32 billion, up 15 percent from the corresponding days last year. With two weeks to go, it’s already clear this will be the busiest holiday shopping season ever in terms of e-commerce spending.

In the most recent week, four days exceeded the $1 billion sales market. The final weekend before Christmas saw $1.04 billion in sales, the second-heaviest weekend of spending on record.

“With only a few more days until Christmas, the preponderance of Americans’ late season holiday shopping will shift to brick-and-mortar retail, although the procrastinators among us will still be able to take advantage of expedited shipping and buy online up to and including the day before Christmas Eve with the guarantee of having their gifts delivered in time for the holiday,” said comScore chairman Gian Fulgoni. “In total, we will see another $5 or $6 billion in e-commerce spending over the remainder of December to finish off what has clearly been an outstanding season for online retailers.”
