Yes, buying items in bulk definitely saves money, but what if you don’t use five gallons of milk per week? If you have the storage space in your freezer, it can be a good way to save trips to the store and get even more savings out of your membership to a bulk-buying club like BJ’s or Costco.

I get home milk delivery and have accidentally frozen a few half-gallons in my day, which doesn’t end well. You can do it on purpose, too, and also freeze other dairy products like cheese, eggs, and butter if you find a good sale and like to stock up.

Milk: Pour out a small amount–you really only need to remove less than a cup–so the container doesn’t expand and explode. It will keep for about a month. Remove your next gallon about 24 hours before you need it. Don’t drink half-thawed milk because it will taste watery and gross.

Cheese: Freeze in bricks, or shred it first! It can last about six months, but cheese that you plan to slice for a party or for grilled cheese sandwiches shouldn’t be frozen, because it will end up crumbly.

Eggs: You can freeze them, but as anyone who has accidentally turned their fridge temperature too cold can tell you, you need to crack them first. This video demonstrates eggs being lightly whisked and stored in an ice cube tray. Eggs can keep for about a year.

Butter: Unsalted butter lasts a month or so, and salted butter can last up to six months. This one’s easy: just put the containers in the freezer.
