What's your grocery and food budget? We currently spend around $600 for 2 people. That includes eating out (usually less than $50 month total). That also includes all of our other household supplies (soap, napkins, paper plates, toilet paper, deoderant, sandwhich bags, etc). It seems like too much of a hassle to separate that stuff out when it's on the same receipts.
That number seems high based on what i've read around the forums, but I want to check where everyone else is at. I have already lowered that number by eliminating fast food, soda, and bringing my lunch to work. I also try to buy in bulk, freeze stuff, and make multiple meals at a time. We also like to have bbqs with family (already had 3 this month) and eat some stuff that is not the cheapest option (but we enjoy it and don't want to give it up) like cheese burgers, fish, fresh fruits, and the wife has a penchant for making frequent desserts.
