Cheapest supermarket?

[Sundaynightterrors]

For every day family shop with a mixture of own brands and well known ones. Aldi? Lidl? Or somewhere else?

I've compared by pricing the same basket of goods several times and found in June this year, setting the Tesco basket at 100%.
The other supermarkets were Aldi 94%, Sainsbury 102%, Asda 103%, Morrisons 104%, Waitrose 137%. Some variation is due to exactly the same item not being available everywhere, the bulk of the saving in Aldi was on a few items. Before Asda was taken over by TDR Capital it was within a few pence of Tesco. Iceland I've tried to price but the restricted range made it impossible. these figures were based on a basket that cost about £55 in Tesco, it only included things I buy regularly though I probably wouldn't buy them all the same week.
