Our family used to spend approximately $100/week on groceries. I wouldn't say it was actually a budget of $100/week since I never really "budgeted" a certain amount for groceries. We would go shopping once a week and that is what it would average out to be. Since I have been couponing regularly and "budgeting", I aspire to reach a goal of $40/week for groceries. Some weeks I do well at that budget amount but others are still a little over that amount.
