Good product but too costly

I have been using this product for years, it keeps my pool's balanced and clean with less maintenance. However, what I'm only disappointed is the cost which doubled in the past three years, the inflation made me sick !!! Hope the price is brought down soon.

lower the regular price.

Better price! Chlorine has gotten so expensive. There is no real reason for that now the plants are up and running. Sam's club needs to sell it at 79.99 regular price.

Easy measure, simple dissolve, consistent size

We picked up Members Mark chlorine granules for our pool. The price was great and the product was consistent in size. We were grateful for this product as it helped save the day for our salt pool when our generator went out for a short period of time. Sams Club to the rescue.
