I keep mine in zip lock bags in a rubber ware bin in a spare room. I have a huge collection and decided that's the safest bet for me.

Onced thawed, I'd hate to refreeze them due to condensation. If you don't use a deep freezer, the rest automatically thaws. That's why I don't keep anything in the fridge freezer. Freezer burn ice cream sucks.
