Do you work to a fixed budget or just see how it goes? I assumed most people at least look at the prices of what they are buying, and worked to an approximate weekly spend, but then there was that programme on recently about how to show a family they could eat better/cheaper etc and some family on it spent £20000 a year on their food?!?!?!?!?!?! (What was it called)?
We are a family of four who, apart from the occasional lunch out eat the vast majority of our food at home, don't go to the pub very often so booze is all at home and I reckon we spend between 150-200 a week, a bit more if we have friends over for dinner. I am quite careful about not being too extravagant but don't buy "value". Absolutely no ready meals in there, though can't claim we don't cheat a bit from time to time. We also try hard to use leftovers to reduce waste.
No idea if we are under or over average.... or fairly typical?
