You clearly aren’t trying very hard! Do you only buy basic stuff, and then in small quantities? I would have to try very hard to spend just £100 per week of four
Our shopping averages £100 a week for 5 with no particular attempt at budgeting - but like the pp, I detest food waste so I’m careful not to overbuy.
I also don’t like spending for spendings sake so I always buy budget/value options when there’s no difference - I wouldn’t chuck in the £1.10 tin of tomatoes for example when the £0.30 tin is literally exactly the same just without the pretty label.
We eat very well and healthily but I suppose our natural way of shopping is to buy ‘basics’ - lots of unprocessed meat, lentils, chickpeas, beans, eggs as protein. Natural yoghurts, plain cheeses, a ridiculous amount of milk. Porridge oats for breakfast. A fuck tonne of fruit and veg which I struggle to cram into our (2!) fridges for a week. Whole meal bread and pasta, brown rice and a massive sack of potatoes a month that lives under the stairs.
We’ve got a cupboard full of dried herbs and spices and nearly everything is made from scratch.
I can’t imagine how I could possibly spend £200 + a week on food tbh.
I would imagine I’d either have to buy branded items for the sake of it (like tinned tomatoes, porridge oats etc) be buying a lot of premium priced convenience stuff or fancier versions of things, like flavoured yoghurts, branded cereals, coated meat, fancy cheeses, ready made branded sauces...none of which i’d want to buy for health reasons anyway.
