Latest research from the US confirms predictions of a bumper holiday season for online retailers.

According to the weekly eSpending report from Goldman Sachs, Harris Interactive and Nielsen/NetRatings, stateside shoppers paid out $2.95 billion (€2.38bn; £1.67bn) online during the second week of December, a 48% hike on the same period last year.

Internet expenditure has been booming across the holiday season. In the period from November 1 to December 12, consumers spent $13bn on non-travel purchases, a rise of 46% year-on-year.

During this period, the biggest category by expenditure was apparel. Shoppers spent $2.5bn on clothes via the internet, a 35% year-on-year rise. Next came toys and video games on $1.6bn (+27%), consumer electronics on $1.4bn (+12%) and books on $1bn (+33%).

A greater proportion of holiday expenditure is now going online. In the six weeks from November 1, surveyed shoppers spent 20.5% of their seasonal budgets online, up from 16% a year ago.

Bricks-and-mortar stores appear to be losing out as a result. The survey found that 72.9% of holiday expenditure went to shops over the same period, down from 76.8% last year.
