1 case of Clorax Bleach, 3 bottles, 182oz for $9.99. 50 cents off regular price of $10.49 plus received a $2.50 coupon off the next shopping trip. This is 1.83 cents per ounce of 6% chlorine.
I picked up two cases to use when opening the pool. I am waiting for the pool store to get in fresh Liquid Chlorine (12%).
I will post local pool store chlorine price per ounce when I pick up a 5Gal container.
