Cutting the cost
A full freezer runs more efficiently, so fill the gaps with water bottles if it's half-empty. Keep it somewhere cool rather than a hot garage or laundry, and defrost it before the ice builds up thick, since heavy frost makes it work harder. Check the lid seals firmly all round. If it's an old unit sitting barely used, consolidating and switching it off can quietly save plenty.
