Cat,Thats very expensive, I searched for a few weeks to find 12.5% bleach, after I ran out of the bleach that came with the rig I purchased, and finally found a good deal.I purchased a 55gal. drum for 82.00 thats about 1.49 a gal. I was able to pick it up so no shipping.That helped also was made the day I ordered so it was fresh at 15%.There were a few other places that were about 45min to 1hr away there prices were 2.00 and 1.89 per gal that sounds very expensive to me.
