The National Consumer Agency says an increasing number of Irish people are shopping around to save money on their grocery bills.
In a report out today, it says almost one-third of shoppers spread their spending across a number of supermarkets.
It also revealed that more than half of consumers shop at discount stores like Aldi and Lidl.
However, Tesco, Dunnes and Supervalu are still the main supermarkets used by Irish shoppers, who spend an average of €150 per week on groceries.
