The retailer has announced a 13 per cent rise in sales throughout the final weeks of 2012, celebrating significant growth both online and in-store.
Web sales were up by 44 per cent on 2011, whilst stores continued to draw in customers through the firm's annual end of year sales event by posting sales of £645 million for the five-week period.
Electrical goods and home technology proved to be key categories as sales in these areas rose by 31 per cent on the previous year.
The firm also experienced a record-breaking first day of its Boxing Day sales event, recording sales figures of £31.7m.
"In an economic climate which continues to be volatile, to have achieved these results is testimony to the strength of the John Lewis brand and the commitment of all our partners to give outstanding service," said Andy Street, John Lewis' managing director.
The retailer's sales were up by 14.8 per cent in total, with online business now accounting for a quarter of the firm's sales.
"That hour when we opened our clearance website, at five o'clock on Christmas Eve, was our single busiest day online, ever," Mr Street continued.
These figures echo reports from other retailers who celebrated record Boxing Day sales, with information service Experian reporting that over 113 million visits were made to retailers' websites on the day after Christmas.
