Good question! No real secrets here but more of a consistent practice: keeping a monthly record of expenses which we go through as a family. We tally up the spending for each week and then review where we can pull back or budget better, being mindful of our needs vs wants. It's amazing how this simple habit keeps us on track and stops frivolous purchases because we're held accountable at the end of each week! Also, I try not to go groceries shopping when I'm hungry - that's a surefire way to overspend!
