I am also a family of 2 and I budget approx $200 a week for food. Sometimes I can be under and sometimes I am over. I don’t buy coffee at work, I take it to work in a thermos, we both pack work lunches, and we cook at home. We shop at 2 grocery stores, one is a cheaper type store and one is definitely more expensive. We only have these 2 options in our area. We do eat out, but not all the time, so I have a bit extra set aside on top for that as well. If I could do it for less I would. I try to buy the generic brands where I can, and we meal plan. I think if that’s what it costs then that’s what it costs. Some places are just more expensive. I definitely find I am more likely to be under budget if I meal plan though.
