Just thought I'd let you all know of a very reliable and inexpensive supplier for pond supplies. You will find them on the net by typing "Pondliners Direct" into your search engine. We ordered pond liner, underlay and double sided waterproof tape on a Friday afternoon. By the following Monday it had arrived!! Postage and package was remarkably cheap considering it came from England all the way to West Lothian in Scotland by courier. Under Â£9!!!!!!!! The goods themselves were purchased at approx 1/3 off normal retail suppliers prices. Excellent quality and service.
