I received an email about blood pressure, so I looked into it. The article after finally getting towards the end said the answer was in the book that cost $19.99 so I went to order book and at the bottom line once I put in my bank card info it showed me $37.00 and that I had joined a membership of 1 year. It never mentioned anything about a membership. When I tried to respond back to them to cancel, the email address did not work. I finally got a number for them and had to hold for 10 min or more. They told me they would reimburse me my $37.00.
