Actually, PoolSupplies.com is Leisureliving.com, is FantaSea.com--and ALL of them are Island Pools, based in Grand Island, NY--between Buffalo and Niagra Falls.

I bought my FantaSea from them and have bought a lot of stuff from them. Their prices generally are pretty good and they do stand behind their products.

They are probably as good a place as any to order an on-line liner. But you can try SpecialtyPools, RedsPools--and bunches of others.
