Northern Ireland's grocery market grew by nearly 13% during 2020 with giants like Tesco and Sainsbury's increasing sales significantly, according to a report.
But NI's big Christmas food shop was less of a splash than usual, research company Kantar said.
Sales of turkey were down 1.4%, while we also spent less on indulgent items like cheese, cakes, seasonal biscuits and smoked fish.
However, shoppers forked out more for cheaper treats like ice cream, crisps, chocolate, sweets and nuts, sales of which were all up. And the closure of pubs and restaurants over the festive period put fizz into alcohol sales which were up 36.7% to £100m.
Of the big four grocers, discount supermarket Lidl has reported the strongest sales growth over the last year, at 19.7%.
But symbol retailers like Spar and Centra achieved the strongest growth of all types of grocer at 24%, leaving them with a market share of 8.8%.
Kantar said 2020 had been an "extraordinary" year for the sector, with growth accelerating from 0.4% a year earlier.
Big supermarkets were the only retailers to stay consistently open during 2020 as other non-essential retailers were affected by intermittent lockdowns.
However, coronavirus restrictions meant that our visits to supermarkets were less frequently - though Kantar said that nine out of 10 of us shopped in Tesco at some point.
Over the 12 weeks to Christmas, grocery sales were up nearly 15%.
The report covers a period before the adoption of the NI Protocol on New Year's Eve translated into supply problems at some supermarkets.
While Lidl had claimed the greatest sales surge, it remained behind Tesco, Sainsbury's and Asda in number one to three position respectively.
Sales at Tesco, which has around 50 stores in NI, had grown by 11.7%, keeping its hold on the top spot safe with a market share of 35.2%.
Meanwhile, Sainsbury's sales were up 12.8%, leaving it safe at number two with a 17% share. It has 13 stores here.
Asda's sales, meanwile, grew by 8.3%, giving its 17 Northern Ireland stores a market share of 15.9%.
In fourth place, Lidl - with 40 stores of a smaller format than its competitors - has a market share of 6.4%.
Emer Healy, retail analyst at Kantar, said: "Looking back over the course of an extraordinary year, national restrictions and various lockdowns saw shoppers visit supermarkets 18.5 fewer times while average basket sizes jumped by 17% in 2020.
"Tesco maintained its position as Northern Ireland's biggest grocer with 35.2% of the market this period. More than nine in 10 Northern Irish households visited the store in 2020 to help it grow sales by 11.7%.
"Sainsbury's saw the second highest growth of the top four retailers, with sales up by 12.8%.
"Its shoppers bucked a wider trend of declining footfall and only made one fewer trip than this time last year, aiding growth for the retailer." And she said Asda's sales increase of 8.3% came as consumers spent 25.6% more each time they shopped there.
