I was coaxed into purchasing The Blood Pressure Solution book after watching the video. When I reached the payment part, the screen conked out. Since I had keyed in my card information, I called them up, and they replied that they would get back to me. To be fair to them, they called but were not ready to listen to my problem and started asking a lot of irrelevant questions. Frustrated and irritated, I just asked them to cancel my order. I have learned a precious lesson. Do not give any card information to these type of dodgy sites.
