We bought a used hot tub and started to replace all the parts. When we got to the filter, we had a lot of trouble finding it. It seemed to be no longer available. Every store I went to, I was told they could not help me. I went to Pinch A Penny and the sales clerk started searching through each filter. He helped me locate one the exact same size as my old filter. It works perfectly! If I had to listened to the other stores, I would have thought I could not buy another filter. The fact that Pinch A Penny took the time to resolve my problem, means that I will continue to shop with them. They have a great selection of both pool and hot tub products. From now on we will be buying all of our pool and hot tub supplies from them.
