Locally, the price of 10% Wal-Mart pool bleach is $3.22/gal. and the jugs are quite old (3-6mo.+). So, having calculated the labeled chlorine content and still at Wal-Mart, we are buying the green labeled 6.0% "cleaning" bleach for $1.77/gal. It works out to be cheaper.

Do we have a calculator here?
