FC&A Publishing Sends unordered books to senior citizens Peachtree City Georgia

My wife, 81 years old & nearly computer illiterate & with no "smart phone" received a book in the mail. At first we questioned each other about why it was ordered. Then we realized neither of us had ordered it.  I did a search & found that the company does this with books from many different areas of interest. I checked with the post office & they told me that I was under no obligation to send money or pay to return the book. So, it's into the recycle bin with it & any other correspondence we may receive from them.
