I think what happened is it used to be cheap and economical to buy non scented 8.25% bleach at a lot of stores, including wally's.Wal marts all over western North Carolina are out of the pool essentials LC too. No idea what happened. It’s been an easy get until this point.
Now the have increased water and decreased the bleach content all for the same price. So really a huge price hike has sent everyone scrambling for some good and relatively inexpensive stuff.
Water's not cheap to bottle and ship you know. And the retail world just increased your shipping and container fees by almost a third.
