One lucky shopper will win £20,000 of Aldi vouchers – equivalent to four years’ worth of free shopping – in the giveaway, the supermarket said.
The average shopper in the store spends £5,000 per year on groceries.
The competition is open to all Aldi shoppers who apply before the end of January, who must send an email to aldicheapestsupermarket@clarioncomms.co.uk with their full name, age and postal address.
Julie Ashfield, managing director of buying at Aldi, said the competition celebrated the company’s fourth win of the title of the UK’s cheapest supermarket, awarded by consumer title Which?.
Which? found that Aldi was an average of £131.13 cheaper per month than Waitrose throughout 2024, with Lidl being the second-cheapest supermarket, charging £1.99 more for a representative trolley of groceries on average.

“We’re delighted to have consistently offered top-quality products at the lowest prices across the country,” Ashfield said.
The Which? comparison included a shop of 56 essential items, including milk and butter, and comprised some own-brand items and brands such as Hovis bread and Birds Eye peas. It assessed special offers, but not multi-buy offers.
Top of the traditional supermarkets
The consumer champion’s study named Tesco as the cheapest of the traditional supermarkets, with Waitrose as the most expensive.
Which? also looked at the cost of a longer list of items available in supermarkets, excluding Aldi and Lidl from the comparison as they do not stock the same range of products.
In December, Tesco was the cheapest supermarket – particularly for those using a Clubcard, which offers extra discounts. It was closely followed by Sainsbury’s – which expanded its Aldi Price Match scheme towards the end of last year – and Morrisons for those using loyalty schemes.
A recent study by shopping website WeThrift showed that Tesco’s loyalty scheme was the most generous and easy to use, with Aldi’s reward scheme being the least favourable. Sainsbury’s Nectar was the second-best scheme in the study, with Asda and Co-op coming in joint third place.
