I'll answer here - Asda (on-line) plus Aldi. Top up with milk and bread from local shop. Tesco here has become really pricey and Sainsbury is really expensive. Don't do Morrisons as I lose the will to live when I go in. Don't do Iceland or Farm Foods as I don't buy ready made stuff these days (not anti ready-made, just too expensive for my lot and they don't like it now they have got a taste for home made stuff).
Tesco, Morrison's and Asda all give you a voucher which tells you if you could have got your shopping cheaper elsewhere and by how much. You can then spend this on your next shop.I find that Tesco staff are more efficient and friendly.
sainsburys mainly because i find their quality of food better than the other supermarkets...i do get the odd item from the co-op if im in the village ...i dislike tescos and asda...
Spoilt for choice, Got Tesco, Sainsbury's, Lidl. Aldi quite near. Closest one is Morrisons so I tend to use them. B&M bargains is nearest but it's full of sh1te:-)
