My friend purchased home with a beautiful IG and I am have him using BBB. However, he is giving me a hard time because I told him that I buy Clorox bleach at Sam's Club. It is the three pack of 1.4 gal 6% Clorox for $8.12 ($1.90/gal)

I realize that it is not the most cost efficient (but still very good) and since I have a large pool and use about a case/week....the cases are very convenient to transport and store.

He found this from Ben...and asked for my thoughts...
