I love home delivery!

I love home delivery! I can't lift very much weight such as these Chlorine Tablets, due to prior surgery and back injury. With home delivery I can still purchase items I need and not worry about lifting since it's delivered to my home right up to my door : ) Thank you very kindly for adding this feature it has helped me numerous times with my disability. Your delivery people are always right on time and kind.

I have bought this product several times

I have had two shipments of this product in the past and found many broken tablets upon delivery. However, my first shipments and this last shipment was received with the tablets all intact, as far as I can see. This is a very good product for maintaining the chlorine levels in your pool.

Great Prices for Great Products!

I have purchased Doheny's Tri-Chlor tablets several times. I have a 25,000 gallon pool and it eats all chlorine tablets up in the summer time. Tri-Chlor is the best product I have found for pool maintenance, and Doheny's 50# bucket of 3" tablets is the most economical way to purchase them. The bucket comes in a manufacturer's labeled box and is usually delivered within days of the order, with free shipping. I have compared the pricing on many brands, sizes and distributors, but have found the Doheny's offerings to be the best. I will definitely buy from them again!
