Bargain-hunters may want to think tactically about where they buy their groceries, as a monthly report has revealed they could save as much as £44 on a trolley of 85 items by shopping at a particular supermarket.
Lidl was previously named the nation’s cheapest supermarket, but research conducted by Which? found that in July it was slightly cheaper to shop at Aldi.
The consumer group compared prices for a trolley of 85 items, including both branded and own-brand items, such as milk, pasta and lettuce.
On average, shoppers would have paid £78.50 at Aldi, which beat Lidl by just 96p.
But at one other mainstream supermarket the same trolley-load of products cost £44 more than at Aldi.
Natalie Hitchins, head of home products and services at Which?, said: “Our analysis shows that where you shop can save you almost £45 on the price you pay on your weekly groceries, so if you are on a budget you might want to head to one of the discounters instead of your usual go-to supermarket.
“If your choice of supermarket is limited, you might still be able to save money by swapping your usual branded items for own-brand alternatives and being wary of offers that make you buy more than you need, as these may not necessarily be the cheapest option.”
Asda was the cheapest of the ‘big four’ supermarkets, with the bill for the 85 items coming to £88.29. Whereas at Waitrose the total was £122.47.
Here’s how much the Which? trolley of groceries cost at eight different supermarkets:
Aldi - £78.50
Lidl - £79.46
Asda - £88.29
Tesco - £98.48
Morrisons - £99.30
Sainsbury's - £103.26
Ocado - £117.85
Waitrose - £122.47
Shoppers made fewer trips to food stores the week after government rules on mandatory face coverings were introduced, according to a separate study.
Market research firm Kantar found that two million fewer trips to stores were taken after the rule was introduced in England on 24 July, which the researchers say indicates that shoppers needed time to adjust to the new regulations.
