Aldi was the cheapest supermarket for a basket of essential goods last week, a price comparison has found.
A basket of 33 common items cost £51.35 at the German grocer, compared to £78.26 at the highest priced supermarket.
The same 33 goods would have cost shoppers £60.43 at Sainsbury's, £64.25 at Tesco, £61.92 at Morrisons and £78.26 at Waitrose, The Grocer comparison found.
The best priced Big Four supermarket was Asda, where a food shop would have cost consumers £58.33 on average last week.
The trade publication's 'Grocer 33' price test compares prices each week using mystery shoppers.
Lidl was named the cheapest grocer the week before, when an identical trolley of goods amounted to £53.06. Lidl did not feature in last week's price test.
Food prices are rising at near-record levels as the cost of living crisis bites, according to recent data.
Kantar, which records prices, said inflation in February was 4.3%, with prices rising fastest for savoury snacks, fresh beef, and cat food, while the cost of bacon, beer, lager, and spirits fell.
Julie Ashfield, managing director of Buying at Aldi, said: “The cost of their weekly shop is more important than ever for many people right now, and it’s great that an independent price comparison has once again recognised that Aldi won’t be beaten on price.
“We are the lowest priced supermarket in Britain and our customers always pay less for their shop with Aldi, which is also why we were named Cheapest Supermarket of the Year by consumer champion Which?.”
However, while Aldi came top on prices, it claimed the lowest spot for customer service.
Tesco was named the best for overall customer happiness, with Sainsbury's in second place, followed by Morrisons.
The Grocer comparison looked at Asda, Morrisons, Sainsbury's, Tesco, Waitrose and Aldi.
It normally includes Iceland, Lidl, Amazon, M&S and Ocado too, but did not this time.

Last month, Lidl was voted the cheapest supermarket by consumer group Which? in its own rankings.
The monthly price test by Which? compared the cost of 23 essential goods including own-brands and items such as Hovis bread over the course of 28 days – to reveal the cheapest grocer that month.
It found that, on average, shoppers would have paid £24.21 at Lidl.
It beat rival discounter Aldi by just 62p. Meanwhile, the most expensive supermarket was £9.50 pricier than Lidl for an equivalent basket of groceries.
Groceries with some of the biggest price differences included PG Tips tea bags, which had a difference of £1.52 between Lidl and Waitrose, and own-label seedless grapes, which had a difference of £1.41.
