A huge investigation has taken place to reveal the cheapest supermarket.
Aldi and Lidl battled it out for the top spot – with Lidl just 21p cheaper in a basket of 78 items.
The research was carried out by Which? and it also found that in a shop of more items, Asda comes on top.
Asda is also the least expensive of the big four supermarkets, according to researchers.
Which? compared a trolley of groceries and household essentials, to make it a fair study.
Some of the products in the sample shop were own brand items like pasta, olive oil and salad tomatoes, and branded items like Hovis wholemeal bread were also included.
If found you could save more than £41 on those items and more than £100 on the bigger shop.
