Aldi, Lidl, Netto. And suddenly the weekly food bill is less than £28. If I have to go to TESCO & Co once in a while, I make sure I only buy from the bottom shelves, that's where the cheaper, less easy-to-reach articles are. For example, TESCO brand toothpaste for 17p, TESCO brand shampoo (1litre) for 19p instead of £2.29 for the brand names.
