Is AmeriMark Easy Living Membership a total scam?

About 1 month ago I ordered something from the AmeriMark Catalog for my disabled SIL, who does not have a credit card or computer access.
Two weeks later I received a phone call from a non-native English speaker offering a service that wou be charged to my credit card. Of course I refused several times and made it quite clear I did not need the service; I do not want the service; and do not want anyone charging my credit card for anything. And do not call me again. However. today I received a notice that I had signed up for AmeriMark Easy Living Program and my credit card will be charged $3.99 in 4 days and $24.99 per month thereafter.
Wiothin 5 minutes of opening the letter I called AMEX and told them about the scam and to stop the fraudulent charges. I also reported the scam to a couple of websites.
But out of curiosity I was wondering what the “service” actually provides. Are there people out there who use this service? All I can find are complaints. Many, many complaints.
Does the Ameriark Easy Living Program provide a shred of useful service or is it the total scam it appears to be?
