we spend $100 a week for a family of 3. That includes household items. One of the reasons that makes it simple to shop an stay under budget is because we plan out or meals, instead for chopping randomly and throw it in the fridge. If we have money left over, we buy snacks, etc., in case some of us get hungry. My wife and I have stopped going out for lunch and thus bring left overs or bag lunches to work.
