When budgeting for a family each month, it doesn't take long to figure out that groceries add up. According to the U.S. Department of Agriculture, a family of four spends anywhere from $500 to $1,000 each month. It really depends on a family's spending habits.
In many cases, families can save money when buying items in bulk.
"Household items or anything you're going to use daily like paper towels, toilet paper, trash bags, spices or mayonnaise. It's a good idea to buy these things at say, a Sam's Club."
Dr. Brian Strow says you should be careful buying food items that can spoil in bulk. "If you're not going to use them before they spoil, is it really a good deal? Are you saving any money?"
Another thing to watch for is whether buying in bulk is causing you to eat in bulk. Often the availability of snack foods just means they get eaten faster.
"Sometimes it can really save you money, sometimes it doesn't."
