Liquid shock in Maryland

Anyone have any advice on the best place to get liquid shock in MD. I'm in Howard county. For the past 7 years I've been getting 4 packs of Austin’s Pool Tech Shock (liquid chlorine 12.5%) from the BJs wholesale club in Columbia, but I was there this week and they didn't have it. Maybe too soon, but they had it this time last year. Thanks!

Pretty far out of your way but Clearwater always has some in stock. They just bought ABC Pools in white marsh if you ever find yourself north of Baltimore. I haven't been to that location yet as I am in Bel Air but it's supposed to be a bigger store than Bel Air. The Bel Air store always has a bunch of 12.5 in stock.

Walmart, Home Depot (Catonsville has 10%), Lowes. Mostly 10% at these stores. You can check
various store availability online. Look for pool supply stores if you haven’t already.
