Sales at department store John Lewis jumped to £124.2 million last week, up 9.3 per cent on the same period last year as its online offering continues to grow, new figures released today show.

In the week to Saturday December 1st 2012, online sales surged to £37.9 million, making it the best week ever for its multichannel offering while overall sales saw the retailer report its third biggest ever sales week.

Sales rose 13.3 per cent on the previous week as shoppers rushed to buy online ahead of Cyber Monday today though John Lewis noted that today‘s online traffic is likely to further boost sales across its digital offer.

On the year‘s busiest online shopping day, John Lewis expects sales of the iPad mini, Beats headphones and Sonos wireless music systems to drive growth while its click & collect service , which allows shoppers to buy online and collect from either a John Lewis or Waitrose branch, is braced for an unprecedented number of customers.

John Lewis‘ Head of Selling Operations Maggie Poteous, said of the strong results: “This week has seen another strong performance and momentum is building as we enter December.

“All areas from toys, to bedding and ready-made curtains, to tablets are performing very well.

“As well as buying gifts and getting their homes ready for the festive period, customers are also ensuring they keep warm with cold-weather clothing and heaters selling fast.

“Online sales soared to £37.9 million last week, a record week for johnlewis.com and a great result ahead of Mega Monday when we expect to see another surge in trade.”
