The week before Christmas was Sainsbury's strongest seven days of trading ever. The UK's number-three grocer served a record number of customers, with transactions exceeding 27 million.
The supermarket also enjoyed its best Christmas Eve as it raked in over £100 million in sales.
Non-food continued to perform well, growing at a faster rate than Sainsbury's food offering.
Online, sales grew an impressive 15 per cent as Sainsbury's delivered a record 200,000 food orders.
In the quarter Sainsbury's added 496,000 square-feet of floorspace.
