You may want to double check the strength. I think HEB dropped their bleach down to 6% like everyone elseI'm probably too late for you, but in Austin I've been going to HEB for 121 oz of 8.25% at $2.59, since Walmart lowered their laundry bleach to %6. Walmart does sometimes have full-gallon two-packs of 10% which is on par with HEB, but it is usually sold out. I haven't tried Austin pools stores in a while. I found if they even had chlorine it was ancient, because they don't believe in using it. People in Houston and Dallas have better options.
