Reena Sewraz, Which? retail editor, said: “The cost of living crisis has seen food and drink prices put huge pressure on household budgets.
“It is no surprise to see many people turning to discounters like Aldi when our research shows they could save up to £22 on a typical shop.
“Our findings show that while prices are going up, some supermarkets are significantly more expensive than others.”
Shoppers should remember to compare prices before hitting the aisles, as supermarkets change prices regularly.
It’s also important to note that this is just a snapshot look at prices based on a selected shop, so your grocery order may be cheaper elsewhere.
The Sun approached Sainsbury’s, Tesco, Aldi, Lidl and Ocado for a comment.
An Asda spokesperson said the supermarket was working hard to keep prices “in check” for customers.
They added: “Recently we also announced that we would be freezing the prices of over 500 popular branded and own label products, more than half of which are fresh meat, dairy, fruit and vegetable products until the end of May.”
A Waitrose spokesperson said the supermarket was “determined” to keep prices down and has committed £100million to lower prices on hundreds of products.
They added: “Our customers know by shopping with us, they can trust our sustainability credentials, and choose from a fantastic range at outstanding value and quality.”
A Morrisons spokesperson said it was working hard to keep prices down amidst an “unprecedented period of inflation“.
They added: “We recently reduced the price of 1,000 popular products and remain committed to doing all we can to help when it comes to the cost of grocery shopping.”
