It's been many years since I last bought a liner for our 18 ft. Round aboveground pool. You guys were very quick in shipping my order. Received everything no damage boxes. I can't wait to install it in late April to early May. Would love to tell you more about that timeline. Thanks.

The liner was very affordable, after receiving a quote of $2000 of putting a liner in from a pool company we decided to buy a liner from this store. They delivered in 3 days, it was very easy to install, very pleased and will purchase again.
