The top is for my frozen mice for my corn snakes (I feed the BP live since I can't fit mice and rats in that freezer...it holds a lot...just not all of that) and the bottom for my cokes. It will be hard to find something under $80 unless you look on craigslist for a chest freezer. Sometimes you can find them for $50-$100 if you need something a little bigger.
