I freeze like crazy, and put everything in glass containers and love them. It's so much easier since I bought them. I won't use plastic for health reasons, and they were also disorganized, would slide all over, would stain or shatter if I dropped them when taking them out of the freezer. It was just a mess. The glass square ones are really stackable and you can maximize your freezer space this way. I bought 2 big boxes of glass containers from Bed Bath and Beyond and they are more than enough. I keep my freezer completely full and there's enough for extras for packing lunch, or leftovers for the fridge, etc. I think they would have been $50, but I had coupons and some credit card points cash cards, so they were much less. And they will last forever.
