Sorry for the rant.
It was only yesterday that I discovered that Red Devil Lye is gone-ola by several years. About the time I bought my last.

After a lot of internet searching I found the Lowe's has a 2 lb can of Roebic Crystal drain cleaner (IIRC) for $8.

You might be able to get battery acid still from NAPA.

You can also get weaker sulfuric acid from sodium bisulfate, aka pool pH decreaser. $6 for 3 lbs, typically. I use it for stop bath. And the pool.
