Cheapest Supermarket May 2023

Updated: Jun 26, 2023

What are the Monthly Supermarket Price Comparison studies?

We compare how much the big 3 supermarkets charge for a basket of groceries containing a mixture of well-known brands across a number of categories including dairy, household cleaning and food cupboard. We also include own-brand meat and fruit & veg items.

In addition, we check the prices of a baskets of dozens of own-brand grocery items at Aldi and assess versus a comparable basket of own-brand items at Dunnes Stores, Supervalu and Tesco.

How we calculate the average prices

We check each item in both studies over a dozen times each month and work out the average price over the course of the month.

Our study includes short-term promotions where the cost of buying an individual item is discounted. However multi-purchase (for example: 'buy 3 for €10') promotions aren't included.

The products are comparable. In some instances there are slight variations in sizes/weights between the own-brand products at the different supermarkets.
