Very surprised at some of the replies here
I'm a single woman, I probably spend less than that. I don't buy work lunch out and never ever buy coffee out, there's coffee in the office!
Left to myself, I'd never eat out unless someone's birthday etc. I compromise on about 2 a month to keep friends and family happy, but it's always with a half price voucher or something. If he doesn't eat out at all, totally possible. I shop at Aldi. Their meat, fruit and veg is actually better than other big supermarkets. I batch cook.
Someone mentioned washing powder. As a singleton I get through a box of that in about six months, so I wouldn't even put it on a monthly bill.
I'm saving for early retirement. Handing Pret £3 for a sandwich? No way. My sister spends £5 a day on lunch at least. But she's happy to work till she drops, so that's different.
At the moment my extra expense is protein powder because I'm on mega muscle building workouts. Even that's not bad as I only ever get it on Amazon offers. But I reckon if I calculate over a year, even that included would leave me at £80 a month.
You can also spend a lot on cleaning products I find, but I don't.
When I shop for my folks, I'm horrified at the cost of things like that in comparison to Aldi. They like their brands!
