I am very disappointed in the customer service I received here. As first time pool owners, we bought several supplies. There were a few things we ended up not needing because our friends had a bunch of chlorine tabs etc. A few days later, I took the items back unopened and with a receipt and they wouldn't take it back. Apparently they don't take any returns on chemicals only they NEVER mentioned this to us at time of purchase and there is nothing on the receipt. It's only $30 but if feels like they are trying to take advantage of people. I will not purchase from this place again!
