I wonder what's in there?

Do you find yourself going to the grocery store only to find out when you get home that you already had half the items you just purchased? I keep two magnetic pads on the side of my refrigerator. One is a grocery list. The other is to list all the items in the freezer. When I use something I cross it off and when I grocery shop, I make a new list or add to the existing one. Works great and you don’t ever have to wonder what’s in there. This little hint saves on waste too because you use the food before it ends up pushed to the back and freezer burned.
