Chlorine Shortage -  bought one 40 pound container of tablets online last week. Free shipping and chlorine arrived early.  And, then went to local Sam’s Club to purchase two additional 40 pound containers this week.  Sam’s Club 40 pounds is at a phenomenal price when other merchants / pool supply companies are charging twice as much (or more!) for the same product.

Chlorine Shortage

Love the tablets and stability of the chlorine mixture. They keep my pool nice and clear for a low cost.

Chlorine tablets low cost

Chlorine tabs are the perfect size for chlorinators. Although the cost is higher than a few years ago, it's still affordable.

Chlorine tabs

Because pools are expensive to build, own and maintain I always look for who has what I need on sale or for the best price. Sam’s has been my go to place for chlorine for 6 years now

Good chlorine at a good price

Couldn't find any tablets with other reatailers that met the same quantity for the price. Looked up sam's club.com, ordered and received delivery the very next day. Conviniently picked up curb side and product was loaded In my vehicle by a professional sam's team member. Highly recommend.

Great value

Each tablet nicely packed so chlorine exposure is less on opening the bucket

These work as expected and they were a good value.

Good value and quality.

Quality

The cost is still too high being that were once $99 per bucket, the cost raised by shortage and no longer a shortage, the manufacturer is still overpricing the tablets

Chlorinate Tablets

Full of stabilizer. Great is you have a sand filter, not so much with a cartridge filter. Had to drain the pool to get rid of the stabilizer. Too much of a good thing is bad.
