We recieve in total 40k a year and just scrape through spending 150pw on groceries. That said, we are living with DFs mum and only pay 200 pw rent. So I guess that stretches our food budget a bit more. I do know, though that the weeks that DF buys his lunch instead of taking food from home, we really struggle and usually have to tell MIL we'll make up the rent next week. For us, take away costs significantly more than healthy food from the supermarket and fruit shop.
