I've been remiss in posting this, but several weeks ago I purchased PP and a bottle of the strips from Bill at Cascade Pond Supply. I'd never used any of the stuff before and wasn't sure what size to buy for my needs etc. so I phoned instead of just placing my order online. He was so pleasant and helpul, didn't mind chatting at all, and even helped me choose the most economical shipping rate (just as fast for less) to my area. The items were shipped and arrived in short order.
It was a real pleasure to do business with him and I'd be happy to recommend him / Cascade Pond Supply. Thanks Bill!
