The shift to online shopping continues apace, the latest figures from Shop Direct confirm.
The company behind the Littlewoods, Very and Isme brands says overall sales were up 5 per cent in the six weeks to 29 December with mobile transactions the biggest driver.
Online sales were 80 per cent of the total over Christmas, up from 74 per cent in 2011.
Shop Direct's chief executive Alex Baldock said: "With consumer confidence remaining subdued, retailers will have to fight even harder to win market share. To ensure we remain a winner, we will continue to invest in delivering a great digital shopping experience for our millions of customers, whenever, wherever and however they choose to shop with us."
Mobile devices were the group's top seller – one tablet was sold every 40 seconds. In fashion, the retailer's own-label dresses were up 32 per cent year on year.
Mr Baldock said: "This Christmas was well ahead of last year against strong comparatives, demonstrating that our combination of great products, market-leading financial services and unique e-commerce capabilities is hitting the right note."
