Shoppers spent £11.7bn over the Christmas period, spending more money on the more premium items over the holidays, according the latest data from Kantar.
In the four weeks to 26 December, shoppers spent £627m on more expensive items, which is 6.8% more than the year previously.
“The appetite to celebrate and splash out that little bit more this year pushed sales of luxury own-brand products up across the board,” said Fraser McKevitt, the head of retail and consumer insight at Kantar, who released the data.
“Tesco’s Finest and Sainsbury’s Taste the Difference are easily the largest premium own-label ranges, but we saw the fastest growth from other ranges such as AsdaExtra Special and Iceland Luxury.”
There was a 31% surge in crisp sales while sparkling and still wines jumped by 22%.
In the four weeks to 26 December, like-for-like grocery price inflation hit 3.5%.
