Aldi has been found to be the UK’s cheapest supermarket when buying a basket of shopping – but Asda came out on top when using a trolley to stock up on a larger amount of supplies.
A basket of 41 grocery items at Aldi cost £72.54 on average across the month of March, compared with £92.55 at Waitrose and £72.79 at Lidl, the Which? consumer watchdog found.
However, when there was a comparison of 137 items, Asda was found to be the cheapest with the final cost coming in at £343.91.
This larger amount of shopping included the original 41 items as well as another 96 including branded products such as Andrex toilet paper and Cathedral City cheese.
Sainsbury’s was the next cheapest when buying 137 items, costing £9.25 more.
Waitrose was £41.83 more expensive than Asda.

Which? said the findings demonstrated that shoppers can make considerable savings on their groceries depending on where they buy their food.
However, it said many of the major supermarkets had not done enough to support their customers during the cost of living crisis.
The watchdog said retailers should be helping customers by making sure affordable basic ranges were available in all branches, including smaller convenience stores, as well as improving unit pricing on all products to allow customers to easily work out the best value.

Which? retail editor Ele Clark said: “We know people are suffering through the worst cost-of-living crisis in decades and the price of food and drink has skyrocketed no matter where you shop.
“However, our monthly supermarket analysis shows you could save £20 on a basket of everyday groceries at the cheapest supermarket compared to the priciest one.
“Supermarkets aren’t currently doing enough to help customers. Which? believes the big retailers have a responsibility to ensure everyone has easy access to basic, affordable food ranges at a store near them, and to provide transparent pricing so people can easily work out which products offer the best value.”
