Meanwhile the same goods were priced at £63.26 at Sainsbury’s, £64.55 at Tesco, £72.73 at Morrisons and £85.40 at Waitrose.

As the cost of living crisis bites, food prices are increasing to record levels with a basket of items at Lidl costing 4.5% more than a year ago (an extra £2.31), despite being crowned the cheapest supermarket.

Is Lidl really the cheapest supermarket?

The Grocer revealed that Lidl was the cheapest supermarket in their latest price test.

It was also voted the cheapest supermarket by consumer group Which? in its own rankings in February.

The monthly price test by Which? compares the cost of 23 essential goods including own-brands and items such as Hovis bread over the course of the month to reveal the cheapest grocer.

It found that, on average, shoppers would have paid £24.21 at Lidl, beating rival Aldi by 62p.

Groceries with some of the biggest price differences included PG Tips tea bags, which had a difference of £1.52 between Lidl and Waitrose - and own-label seedless grapes which had a difference of £1.41.

What about the quality of service at Lidl?

Despite being crowned the cheapest supermarket this month, Lidl came second to last when it comes to service.

The top supermarket for service was Asda, with 85/100, then Waitrose (77/100), Tesco (75/100) and Sainsbury’s (72/100).

The discount supermarket got a score of 65/100 for this, with Morrisons coming last with 58/100.

Why are food prices rising?

Shop prices are rising at the fastest rate for more than a decade as the cost of living crisis worsens.

Grocery prices are rising at 4.3%, data from number crunchers Kantar recorded.

It found the price of savoury snacks, fresh beef and cat food were going up the most.

There are a number of factors behind these increases, but it is largely due to rising prices of raw materials used to manufacture food and the cost of processing, packaging and distribution.

Rising fuel costs have also impacted the cost of producing various food and drinks, while supply chain disruption has also caused issues in the industry.
