Helen Dickinson, chief executive of PRC, said the fall in food prices this year was due to supermarkets delivering less advertising to customers last year.
With the onset of the epidemic in 2020, there were fewer deals and deals in supermarkets to avoid customer presence in products prior to the UK’s first lockout.
However, Ms Dickinson said the fall in prices would not last. He said: “In the coming months, retailers will have to contend with cost pressures coming from the Brexit red-tape, which will increase shipping costs due to international supply problems, as well as rising global food and oil prices.
“Because these costs are filtered out, retailers have no choice but to pass on some of these costs to consumers.”
