Yes, now we have a very careful planned menu in which we aim to get 3/4 or more meals from every meat purchase and never throw away anything from the veggie box.
Still go to our brilliant butcher as meat is better value over the whole week than Lidl - but I did check them out and they are only worth it if you want flashfry type meat - but see above
Mutton chops! a great bargain.
Making own cleaning products
Reusing foil and clingwrap, and freezer bags. No more wipes; much washing of dishcloths.
Much more mending/darning of uniforms.
All biscuits/puddings are now homemade and as freegan as possible -eg we've all been out in the hedgerows harvesting the haws, blackberries and crabapples
I make bread for us all, buy flour in sacks (cheaper that way)
At least two veg only meals every week, and many others where meat is almost a flavouring.
No eating out at all. Anywhere. No drinking out either, not even coffee.
No holidays for the forseeable
All this has cut the food and household bill by 30-40%
