Some frozen food has storage instructions for fridges as well as freezer, especially on the ready meals/pizzas. A lot of it says keep frozen, but sometimes you can store things in the fridge for a few days if you don't have a freezer. We have a big freezer for the UK and bought a chest freezer off our inlaws. Before we had the chest freezer, though, we sometimes would store a few things in the fridge if we were going to eat them in a day or two. I freeze a lot of what I cook, so there isn't always a lot of room. We have more now, of course, but at one time, we were really pressed for space.
