Being very clumsy with social sites, asking your guidance.
At facebook marketplace, saw an advertisement and a "share" option. But found am not in the list of 'groups' nor 'contacts' to choose sharing to. How do I send it to myself as in 'Messenger' ? (purpose is to keep as reference) I do not use facebook on my phone, just in my laptop at home.

 

Whatever search engine you are using (Edge, Google, Firefox, etc.) it will have a way to save internet pages. It's usually a star symbol at the top of the page. When you have the advertisement displayed, select the star to add it to "your favorites".

 

You can send messages to yourself through the latest version of Whatsapp.

 

Arrange with a friend with whom you can share the item. Have them share it back to you.
