SPAR, Eurospar, Vivoxtra and Vivo stores in Northern Ireland have implemented a restriction on the purchase of all products.
The move comes in response to the growing coronavirus pandemic and retailers experiencing a surge in demand for everyday items. Shoppers will not be able to purchase more than three of each item in store.
A company spokesperson said: "Like many retailers across the country, we have experienced a surge in demand for everyday household items and a high degree of panic buying. We would like to reiterate that we are doing everything we can to meet this demand, however we now need to place a restriction on the purchasing of goods to make sure none of our shoppers go without.
"Shoppers will not be able to purchase more than three of each item. This measure has been put in place to protect our shoppers and suppliers, who are also feeling the strain of the increased demand. This way, we believe we can alleviate much of the panic buying, raise supply and meet demand."
