If you wanted to sell me a water purification system, you should have done it like every other legitimate business. The "Package Shipment" flyer is a scam and only used as a tool to get your call. They just want to get a salesman into your home and scare you into thinking your water needs treatment. The interesting thing is, I've been wondering about the quality of my water and probably would have been interested in having it tested, had the company conducted themselves in an ethical manner.
