    It’s a hotly debated topic and one that is often asked in our supermarket savings community – where is the cheapest place to shop?

    The thing is, I don’t really think there is one single answer.

    Sure, for ME, and the things I buy can be a supermarket cheaper.

    However, we don’t have young children, so save yourself the extra costs and nobody in the family will have allergies or food intolerances.

    Just because the basket of groceries I buy a week is cheaper can the things you buy get more expensive.

    Which is the cheapest supermarket in the UK?

    Are you trying to use a little methodology, Which consumer group? monitored food prices in six major supermarkets (* that must have been a fun job *).

    First, they made a shopping list of 22 items that they thought would be in a typical shopping cart.

    Their list included items like private label bread, chips, butter, cheese, detergents, pet food, soft drinks, and other everyday items.

    Then each month they calculated the average price (including discounts but not multibuys) for each item and then compared it.

    So what did they find?

    Without further ado they found the cheapest supermarket in September 2021 … drum roll, please …

    The purchase of 22 items from Aldi totaled £ 24.03, with Lidl being the second cheapest at £ 24.40 and Asda being third at £ 26.19.

    Waitrose (perhaps not that surprising) was the most expensive at £ 33.06.

    Every time they track food prices, the shopping cart they are comparing changes. This is because they make sure that products are available in every store. Foods compared included own-brand, free-range eggs and raspberries, and branded products such as Chicago Town pizzas.

    By looking at prices on a monthly basis you can see how much prices have crept in over the year. And you can tell why budgeting a grocery store is so difficult!

    It was 34p cheaper than its rival Aldi.

    Ocado and Waitrose were at the bottom of the list as the most expensive supermarket.

    What’s wrong with your old research?

    Check food receipt

    While I’m sure which one? did their follow up and research perfectly, not sure if this is a true reflection of how people actually shop.

    Missing supermarkets

    For many years you compared only six supermarkets and missed both Lidl and Aldi by 2020.

    Your justification?

    They used MySupermarket to keep track of prices and since Aldi and Lidl do not offer online shopping, prices were not used.

    They also didn’t monitor grocery prices on Amazon, and buying branded products could save you a lot of money shopping on Amazon Fresh or even Morrisons through Amazon.

    Shopping cart with food

    Natalie Hitchins, which one? Head of Home Products and Services, said:

    “Your weekly supermarket shopping can have a significant impact on your wallet.
