Have been using pool shops for years and switched for price and quantity difference and have been pleased. Had this delivered to door and would tell anyone this is the way to get your pool supplies

Sams has the lowest price on chlorine granules of anywhere I've found, however my pool guy pointed out that the percentage of active ingredient is much lower than other more expensive brands so I have to use twice as much for the same result.

Have used this product for many years. It is high quality, it dissolves and elevates the chlorine levels in the pool quickly. Great to shock your pool or when you have to bring the chlorine levels up rapidly. I highly recommend it

good deal

Pool shock

good price.

Good price

I have been purchasing this item for 3 seasons now and have never had anything but great results. Products I purchased prior to that were always hit and miss (similar to many of the reviews here) but never an issue with this one. On my way to Sam's to buy a new one now. Great price too!

I bought this at the beginning of May to use for the season. BIG MISTAKE! I went through the entire bucket in 2 weeks without seeing an improvement in the water! Realizing my error, I purchased a different product. And the pool cleared up in 2 days! I would have gone back for a refund, but I used the whole bucket!
