Wow TMS that is alot. We feed 4 adults and 1 child for less than $250 per week and that's having meat every night. Use cloth so don't buy nappies though. What does the majority of your money get spent on?
I don't know TBH. We have meat every night, fish 1-2 times a week, we go through a lot of fruit and veg, the kids take a piece of fruit plus cucumber and capsicum sticks to school 5 days a week but then we don't spend money on pre packaged/processed stuff
