You have an Ollie's in Eagleville. I'm near Cookeville, TN and the only liquid chlorine around me is at Ollie's Bargain Outlet Store for cheaper than any bleach or any other chlorine source around my area. At the Cookeville location, they've brought in an entire pallet of fresh stuff (made in March if I recall). I looked at your location and if Ollie's carries liquid chlorine in your area, then it shows that it's only 13 miles center mass of Hatfield to their location in Eagleville. In my area, a full gallon sales for $2.99 at 10% concentration; much cheaper and more potent than any liquid around except a specialty pool store that's sky high in price. I've used it for 2 years and it's potency raises my free chlorine as expected via pool math. It's good stuff cheap to steal their slogan.
