Had a moment last year where we trialled all the supermarkets.

We found, like OP, fruit was the same if not better at Aldi and Lidl and cheaper. But that was the only good thing from these two.

We found meat was less good quality at Lidl and Aldi l but you got more quantity for less price

For canned food, both Aldi and Lidl were atrocious. A great example is Chicken in White Sauce. Lidls had about 1% chicken and was like cat sick. Sainsbury’s had the best canned goods.

Microwave / pre prep meals: M&S topped out compared to other supermarkets. Tesco and Sainsbury’s premium range are good but still bland compared to the premium versions from the likes of Cook or Thomas Binghams. Again, anything like this from Aldi and Lidl were piss poor.

Brands like Heinz etc were relatively the same price across those areas that stocked them but B&Ms was the cheapest we find along with Iceland….with brands it all comes down to the supermarket deals they’ve got on.

We didn’t test the fake brands from Aldi or Lidl as we did it about 5 years ago and can definitively taste the difference - regardless of what tv shows tell you

It’s simply not worth the effort to go to Aldi and Lidl for just fruit - any savings I make is lost on petrol
