Here is a tip that prepares you for a power outage...
Fill containers with water and freeze, then make room in your freezer and store them there. When the power goes out, your freezer becomes an ice chest which will keep frozen items from defrosting, or you can move some of them to the fridge to help keep it cool.
I use washed out milk containers and it can extend the life of frozen and fresh foodstuff for a couple of days.
