Compared to last month, prices have dipped universally. In February, the 72-product shop would cost £4 more at Aldi and £6 more at Lidl.
It comes as shop price inflation eased to 1.3%, the lowest level it’s been since December 2021. This is due to supermarkets going big on Easter deals, says Helen Dickinson, the chief executive of the British Retail Consortium.
The CEO said: “Dairy prices also fell on the month as farmgate prices eased, and retailers worked hard to lower prices for many essentials. In non-food, prices of electricals, clothing and footwear fell as retailers increased promotions to entice consumer spending.”
But, this might not be the case for April, as Dickinson added: “While these figures are good news for consumers, from this month, retailers face significant increased cost pressures that could put progress on bringing down inflation at risk.”
