Online sales in November surged by 16% on last year, as shoppers favoured the internet over the high street.
According to the IMRG Capgemini e-Retail Sales Index, online sales in November rose by 26% compared to October, with sales of accessories recording the biggest spike in growth at 108%.
Clothing sales rose by 18% and footwear increased by 32% in November compared with October.
IMRG chief executive James Roper said: "While we would naturally expect to see a monthly increase in online sales during this time of the year, it is perhaps surprising that we are continuing to see yearly growth during these otherwise difficult times for retailers."
He added: "This is a sure sign that high street retailers should look to diversify their activities by fully embracing the online space, as their customers have. We expect the online sales figure to be even higher next month as people do their last minute Christmas shopping."
By contrast, high street shopper numbers fell by 9.1% over the weekend (December 13-14) against the same weekend last year according to Experian Business Strategies.
IMRG will release figures about yesterday's online sales, which are expected to have shown a significant peak ahead of Christmas, later today. Check back this afternoon for an update.
