Asda was the cheapest supermarket at £418.71. Members of its Rewards scheme also would have earned £2.99 cashback on products with loyalty promotions. The consumer group explained: "We haven't factored this into our main analysis because loyalty members don't receive a discount on the day and cashback is only redeemable at Asda, within a limited period (up to nine months) and in increments of £1.

"Tesco was only 1% pricier than Asda when loyalty card promotions were taken into account (£422.54), but shoppers without a Clubcard would have paid 7% more (£449.99)." Which? added: "Morrisons was the third-cheapest supermarket (£428.32) if you have a More card, and cheaper than Tesco and Sainsbury's if you're not signed up to their loyalty schemes.

"Waitrose was the most expensive supermarket again at £461.10. The total cost of our shop was also 10% more at Sainsbury's if you're not a Nectar member (£459.58)." The Which? shopping list comprises the country’s most popular and widely available groceries, based on extensive market analysis.
