See if there's a Pinch a Penny or an industrial chemical supplier that will sell and refill 2.5 gal containers near you. It's almost always the cheapest way to go. They usually sell 10%+ which makes it even easier. Napco in Houston does this. Not sure who supplies in Austin.

Thanks, but unfortunately Ive already checked with all the pool supply companies in my area (they all only sell the 4x gallons at crazy prices) and I only found one chemical supply company - and they dont offer sodium hypochlorite ?
Looks like it's Walmart or Lowes for me...
