Aldi has been named the UK's top in-store supermarket, beating stiff competition from the "big four" and rival chain Lidl.
The own-brand retailer received a five-star rating for value for money and a 73% overall score for satisfaction, in an annual Which? report, The Mirror reports.
Customers were asked to rate their shopping experience in a range of categories such as in-store appearance and layout, quality of produce, availability of online delivery slots and value for money.
While Aldi received mediocre ratings across all other categories, including two stars for store layout and three stars for the quality of its own-label products and fresh food, price was the most important consideration for customers when choosing where to shop.
Sainsbury's was the highest-scoring online supermarket with an overall customer score of 71% and a four-star rating for the availability of delivery slots.
M&S came second in the in-store supermarkets table after receiving a five-star rating for the appearance and layout of its stores and the quality of its own-label and fresh products.
In joint-third place were Lidl, Tesco and Waitrose. Much like its rival Aldi, Lidl performed well when it came to value for money, achieving four-star ratings, but it failed to impress customers in other categories.
Despite receiving five stars for store layout and food quality, Waitrose was let down by its two-star rating for value for money and was named the most expensive supermarket.
Co-op finished bottom of the in-store shopping table as it failed to impress customers in key categories. It received just one-star for value for money and two-stars for its store layout and food quality.
Harry Rose, at Which said: "Many households have felt the pinch during the pandemic and value for money was the most important factor when shopping in-store in our annual supermarket survey, which explains why Aldi came out on top.
"Online supermarkets have also been a lifeline for many people during the pandemic and while Sainsbury's rose to the challenge by massively increasing its delivery capacity, Ocado's reputation took a hit after the scale of demand meant it stopped accepting new customers and shut down its app at the height of lockdown."
