This Monday (8 December) was the biggest online shopping day of the year, with year-on-year sales values up 14%, as consumers flocked online to purchase Christmas presents.
The Interactive Media In Retail Group (IMRG) said a combination of continuing consumer confidence in online shopping and heavy retailer promotion saw sales of around £320m.
James Roper, CEO of IMRG, said, "Online sales are holding up well, considering the economic conditions, with both volumes and values significantly higher than last year.
"The ratio of researching to buying is also much greater, and researching started earlier this year, as Christmas shoppers work hard to track down the best deals."
He said, "Delivery companies are in sparkling Christmas form as most had geared up for higher volumes than they are receiving so far, so there is plenty of time left for shoppers to bag Yuletide bargains. We may even see next Monday being bigger still, which would be the first time ever that the third Monday in December marked the year's peak."
Jon Prideaux, deputy chief executive of payments service provider SecureTrading, said, "We saw are an 18% increase in the number of transactions, whilst the value of transactions was up around 14% across the market as a whole."
Play.com said it saw an increase of over 45% in the volume of orders it processed on Monday 8 December, when compared to the same Monday the previous year.
