Very competitive price

This is a Walmart/Sams product. Last year, 50 lbs. sold at Sams Club for this same price. This year, the club sells 40 lbs for the same price. Obviously, this product from Walmart--at 50 lbs-- is less expensive per pound, and as a multi-year user, I'm always satisfied that it works.

The price for this 50 lb tub is fantastic. We have priced out this shock with several vendors and found Walmart to have the BEST price. Same product, just more reasonably priced.

Good product, great price!

Been buying chlorine for my pool for over 30 years. This is the first time from this seller but so far, everything is great - 99% sodium dichlor, at a great price (significantly less than my usual source) and shipped free.
