I purchased 55 gallon drums of industrial grade bleach. They contained 15% solution. At $6 each they can't be beat. I also have a buddy that buys food grade products in drums and totes.

I've placed 5 gallon buckets of water in my freezer. My freezer works better, and the water doesn't 'spoil' as fast.
