Facebook saved replies is one facebook page feature I like so much.
Why?
Because it simplifies how I respond to messages I get on the Facebook page where I sell software.
With just a click, I can send download links for the software and it’s pdf guide. I can as well easily send payment details with a click without having to type everytime I want to reply a message.
You can as well personalize the saved replies… 
Cool…huh?
