Grocery is a part of every household’s living expenses. According to United States Department of Agriculture, the cost of food at home for a family of four is around $1000 per month. Mr. Money Mustache shows how to dramatically cut this $1000 grocery bill by over 60%. First you have to nail down how much you want to spend on food per month. Mr. Money Mustache gives us an example of a family of four spending $365 per month or around $1 per day for a family member. The key part is you have to cook at home for your day-to-day foods. By shopping at places like Costco, instead of Whole Foods, you can get the needed ingredients for all your meals. By mixing the expensive foods with cheaper ones, you can make very good meals that average out to $1 per person. Thus you can greatly reduce your grocery bill.
