Cutting the cost

Keep it out of direct sun and away from the oven, and leave a gap behind it so the coils can shed heat. A full fridge holds its temperature better than an empty one, but don't pack it so tightly that air can't move. Check the door seals close cleanly, and vacuum the rear coils now and then. A spare beer fridge in the garage is often the quietest money-drainer in the house.
