It is fairly common for a pool liner box to receive some damage during delivery. If you receive a damaged box, please do not sweat it. In almost all cases, the box gets damaged but not the product. When you open the box, please check the pool liner at the spot the box was damaged. Common sense applies......if something is wrong you will see it, otherwise you are good to go. It is very rare for the pool liner to receive damage, in almost all cases it is just the box. Another thing to remember: you do not have to call and tell us, or you do not have to tip us off.....all other Return and Warranty Policies from LinerWorld will apply.
