I've bought 12.5% liquid chlorine from my local Leslie's for a year or more, as it was a better price than Wallyworld when you took 12.5% vs 10% into account. Yesterday, I called to be sure they still had it in stock (and they hadn't been invaded by the virus locusts looking for any germicides they can find). Yes they had it, but it was no longer $15.99 per box of four 1-gallon jugs. Now, $20...a 25% increase. Anyone else see something like this?
