LONDON, Dec 9 (Reuters) - Monday was the biggest online shopping day in Britain this year, with sales up 14 percent on the comparable day last year to 320 million pounds ($472 million), Internet retail industry group IMRG said on Tuesday.
The second Monday in December has been dubbed "Mega Monday" by the online retail industry because it has traditionally marked the high point of Christmas shopping on the Internet.
But IMRG said that with delivery times improving, there was still time for a stronger performance.
"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," it said.
The rise in sales beat the previous Monday's performance by 20 million pounds and was accompanied by an 18 percent rise in sales volumes.
"Online sales are holding up well, considering the economic conditions," IMRG said.
However, it added that Monday was only the third-biggest day this year in terms of traffic to retail websites, suggesting shoppers are researching thoroughly, both in stores and online, before committing to a purchase. (Reporting by Mark Potter, editing by Will Waterman)
