The supermarket received a €1,000 fine for not including unit pricing on Clubcard promotional shelf-edge labels.
Unit pricing is legally required to help consumers easily compare similar products sold in different sizes.
Judge Anthony Halpin handled the case and applied the Probation Act, directing Tesco to donate €1,000 to the Little Flower Penny Dinners charity.
The case arose from an investigation by the Competition and Consumer Protection Commission (CCPC), following breaches identified during an inspection last August.
In a statement after the ruling, the CCPC emphasised: “Consumers shopping for groceries need to quickly evaluate various factors to determine the best value. Supermarkets must legally display unit pricing to facilitate this process.
“Showing the price per kilo, litre, or metre allows consumers to compare costs of similar products sold in different sizes and prevents misleading practices by packaging or discounts.
“The CCPC urges consumers to check unit prices while shopping and to report any non-compliance to the CCPC.”
