Online spending is expected to rise 15% on last year to £13.16 billion in the run up to Christmas as hard-up shoppers search for bargains on the internet.
Online spend on fashion, footwear and accessories is forecast to grow by 25% to £1.2 billion over the quarter according to a report from the IMRG and Capgemini.
Total average online spend per person will be £215. Although this is a growth of 15%, it is slower than the rate of growth in 2007 when final quarter online sales jumped 54% on 2006.
Monday December 8 is expected to be the biggest Christmas shopping day online when £320m is expected to be spent. Peak shopping time will be between 1pm and 2pm when shoppers are expected to spend £28m. This is double the amount spent by shoppers at last year's peak Christmas hopping hour, at midday on Monday December 11.
IMRG chief executive James Roper said: "British shoppers will beat the crunch with internet prices this Christmas, spending more than a million pounds each week in the run-up. The internet is well established as one of consumers' most powerful economic weapons against tough times."
"Retailers and suppliers will be under extreme pressure to price competitively this year, so there will be a lot of volatility out there - and fantastic bargains - that the internet uniquely enables canny shoppers to find and grab before anyone else gets the chance."
