A little bit of a non-sequitur, but so is my life. Take it from someone who had four different refrigerators in her life in just TWO FREAKING WEEKS quite recently, and had to throw away hundreds of dollars worth of food, this is so very good to know. And no, I'm not exaggerating. I wish I was.
Fill any excess freezer room with O.J or milk containers full of water. The less free space you have in your freezer the less it will run, and the more you'll money save in the long run.
Plus, if there's ever a power outage, the blocks of ice will remain frozen for a while, allowing you to keep food in there much longer than you'd otherwise be able--and, as the ice melts over time, it won't flood the freezer, because it's already in a sealed container.
Another gem from Tricks of the Trade.
I think I'm in love with this site.
