We do it for £70-85 per week. There is always some variance depending on if big purchases (£10 pack of loo rolls or £10 on cat food) are required that week. That’s Tesco.
We eat well but I’m careful. I’m not loyal to brands but go for the special offers. We have it delivered and that means I’m. It tempted so much by things I spot as I go round.
We have chocolate, 1 bottle of wine or beers per week, plus a ready meal for 4 for the weekend (usually costs about £8-£10 for that to include sides like poppadoms or naaans ...lots cheaper than takeaway) and things like biscuits and cake as treats. We have croissants for the weekend and plenty of fruit (but often things like grapes, apples, bananas rather than lots of berries ..perhaps 1 punnet when in season) and don’t buy the cheapest meat, but choose quality bacon and sausages and lowest fat mince which is a bit more expensive.
When I have filled my online trolley and see the total price, if it’s above £85 I look to go back and remove a few items to bring it down a bit.
I’m not someone bulking out with lentils but always put lots of veg in with any casserole type meal. A 750g (large) pack if extra lean mince, made into shepherds pie or lasagne, with lots of veg included, will make enough for 10 portions, so feed us 2.5 meals. A 800g pack of chicken will make us 8 portions so feed us 2 meals. I usually expect a pack of meat to provide 2 meals and not just 1. For lunches we eat nice bread, rolls, a range of cheeses (cheddar, mozarella and Brie) plus good quality ham or chorizo, with crudities or tomatoes, plus some crisps and fruit.
You could try online shopping....it’s easier to remove items before checking out that I. The shop. Or go round with a calculator and when you get beyond your limit, either stop or look in trolley to see what you can do without.
