In September 2021 a basket of 22 branded and unbranded goods from Aldi cost £24.03, while the same basket cost £24.40 at Lidl.
When compared to the most expensive supermarket, Waitrose (no surprise there), Aldi was a huge 38% cheaper for an equivalent basket of items. With Ocado a close second most expensive at £29.84 for the basket of goods.
The same basket at Asda was £26.19, and Sainsbury's came in at £27.95, while Morrisons and Tesco both cost £28.31
Which products were included in the study?
Which? selected a combination of branded and unbranded products that most people buy on a regular basis. The branded products included items such as Andrex toilet paper, Colgate toothpaste and McVitie's digestive biscuits, while some of the unbranded products included own-label items such as mixed peppers, large free-range eggs and semi-skimmed milk.
Julie Ashfield the managing director at Aldi said: 'We're committed to providing our customers the best prices possible, and we’re immensely proud that we have taken the top spot. Being named the UK's cheapest supermarket in September marks our tenth win and we're dedicated to continuing to make life a little easier for our customers'.
This price checking at supermarkets is carried out on a monthly basis and Aldi also topped the list in July 2021 also, while Lidl was the cheapest supermarket in August, according to Which?
Lidl has been knocked off the top spot as Britain's cheapest supermarket, although they came in a very close second so still provide excellent value for money.
The price comparison also found that the difference in the price of PG Tips tea bags in Lidl compared to Waitrose was £1.25
If you exclude Aldi and Lidl, out of the big four grocers (Tesco, Sainsbury's, Asda and Morrisons), Asda remains the cheapest supermarket and has been for more than a year. They've claimed the top spot every month since January 2020.
Retail expert Ed Clarke told The Mirror: The weekly food shop can have a big impact on consumers' pockets, which is why we check hundreds of grocery prices every day.

In other supermarket news, Sainsbury's recently announced that they will be hiring 22,000 new staff before Christmas. That should help get the shelves nicely stocked if the HGV drivers manage to deliver. Morrisons too is spreading a bit of Christmas joy by slashing the price of over 50 products in their run up to Christmas sale.
If you're in London for a bit of Christmas shopping, make sure you visit Harrods Christmas World 2021. It's a must-see.
This Christmas will be challenging for all the supermarket brands due to the ongoing supply chain issues.
The HGV driver crisis couldn't have come at a worse time for retailers. Christmas is the most lucrative time of the year and market analysts Kantar said data they have collected showed that more and more people are heading back in store now that social distancing restrictions have come to an end.
To compound the supply chain problems, Tesco warns Christmas panic buying could be worse than in lockdown, which would result in even more empty shelves for customers.
