Ha! Well I do feel slightly vindicated after the last few posts ...
Chopped and peeled plum Napolina are an identical price at Asda as well. We haven't got a Lidl close to us, Di, the nearest is a bit of a car journey and we have only been there once.
I do agree the price of tinned toms has gone up tremendously, and my 4 for £2 extravaganza should be read in the light of the "standard" price for Napolina which is currently 75p / can in Asda.
Still, I won't be buying any more for a while - at least 8 months !!

We also use them in soups and bolognaises, and I think we do prefer to have a "quality" product.
