Aldi is the best supermarket in the UK according to the annual survey by Which?
They have knocked Waitrose off top spot with the up-market store falling three places.
M&S was rated second with Lidl taking up third place in the in-store category.
The annual supermarket satisfaction survey found that Aldi's offers rated well, as did the quality of its fresh and own-label products and the ease of finding items on its shelves.
Waitrose has been on the top spot, for three years. Its customers gave it a two star rating for its value for money, in contrast to Aldi’s five.
Lidl ranks in third position with five stars for its value for money, but did not do so well with customers when it came to queuing time, staff availability and range of products, reports the Mirror .
What about the big four?
The big four supermarkets - Tesco, Asda, Morrisons and Sainsbury’s - languish at the bottom of the in-store survey.
Customers at Sainsbury’s were least impressed with its special offers and value for money, bringing it in last out of nine supermarkets.
Among online supermarkets, Iceland has claimed the top spot for the third year running, which it shares with Ocado for the first time.
Iceland received five stars for its driver’s service and the availability of delivery slots - with three quarters (76%) of shoppers saying their most recent order was delivered on time.
Asda languishes at the bottom of the online supermarkets table, where it has been for more than a decade.
Launching in 2016, Amazon Fresh has been included in the online survey for the first time, coming in fifth position. The service is only available to certain postcodes in the south east of England.
Alex Neill, at Which? said: "With food costs rising it seems as though shoppers have felt the pinch and are voting with their feet and wallets. Aldi and Lidl have won over their customers with value for money, knocking Waitrose off the top spot.
"The big four supermarkets need to up their game or risk losing their customers to other supermarkets who are doing a better job of giving people what they want.”
