A separate chest freezer can feel like a smart investment for anyone trying to lower grocery costs. It gives you room to buy meat in bulk, store frozen vegetables, preserve seasonal produce, and take advantage of supermarket markdowns. But there is a cost to keeping that extra appliance running, even when you are not actively using it. Depending on its age, size, efficiency, and how often you use the food inside, a second freezer could eat into the savings it was supposed to create. Before filling one with sale items, it is worth looking at the full cost of keeping it.
