Aldi is still the cheapest for a trolley full of groceries – despite price match guarantees and loyalty cards from rivals

New findings reveal that Aldi has been crowned the cheapest supermarket for a trolley load of 65 products, despite its rivals promising to match their price.

In June, the average bill for a trolley of 65 items at Aldi was £118.41, which was £32.60 less than Waitrose, which was the most expensive, at £151.01.

In June, Waitrose was found to be almost 28 per cent more expensive than Aldi for the same products.

Julie Ashfield, Managing Director of Buying at Aldi UK, said: “We are delighted to have been named the cheapest supermarket for the sixth time this year – confirming once again that Aldi’s prices simply cannot be beat even with a loyalty card.

“After all, there is only one supermarket where every price is an Aldi price.

“But it’s not just consistently low prices that customers get from us, it’s also award-winning quality.”

Aldi was £19.10 cheaper than Sainsbury’s Nectar and £15.89 cheaper than a Tesco Clubcard with the same grocery list.

Lidl was the second cheapest supermarket last month with 65 items usually costing £121.31, just £2.90 more than Aldi, according to consumer group Which?

Behind Aldi, Lidl and Tesco Clubcard was Asda, which was the fourth cheapest, with a trolley of goods costing £131.42.

While Waitrose was found to be the most expensive, Morrisons and Ocado were not far behind with average bills of £140.19 and £144.06 respectively.

Who? isn’t releasing the full list of items in the cart, but told This is Money that it includes a number of both branded and own-label items, such as Birds Eye garden peas, Heinz baked beans, milk, butter and Hovis bread.

The findings included prices for shopping with the Nectar loyalty card at Sainsbury’s and the Clubcard at Tesco, which offer cheaper deals in exchange for owning a loyalty card.

Without a Sainsbury’s Nectar card or a Tesco loyalty card, bills at the two supermarkets came to £137.51 and £134.30 respectively. he said.

Ela Clark, which one? retail editor said: “With food prices continuing to squeeze household budgets, it’s no surprise that many people are turning to discounters and Aldi has once again won the title of cheapest supermarket.

“Our analysis shows that Aldi and Lidl are still cheaper than traditional supermarkets, even when you factor in loyalty prices.”

Supermarket price wars

Shoppers have endured steep price hikes at supermarket checkouts amid higher inflation and interest rates.

Supermarkets are locked in a price war to ensure they retain customers and attract a loyal following. Loyalty programs have become big business for many chains.

Some chains, such as Sainsbury’s and Tesco, have increased the use of members-only pricing, meaning customers without a loyalty card will have to pay higher prices for certain products.

While supermarkets are locked in a price war, many consumers are struggling with high bills.

Almost one in four shoppers said they were struggling to stay on top of spiraling bills and make ends meet, Kantar research said last month.

However, Kantar noted in its findings that food prices are beginning to fall.

In June it said: “Costs are falling in almost one-third of the food categories we track, including toilet tissue, butter and milk. That’s a big increase from last year, when only 1 percent of markets were down.”

Inflation rose 2 per cent in the year to May, up from 2.3 per cent in the 12 months to April, the Office for National Statistics said last month.

Lower food prices had the biggest share in the fall in inflation, he added.
