Bill Atkinson Photo Card Shutting Down?

Anybody here use Bill Atkinson Photo Card app?
Got several emails that the card printing service is shutting down.
This was (is?) a really great service and app that allowed you to create post cards and stamps, and have hard copies printed and mailed.
Cannot find anything on the internet about the end of this service. Just wondering if the emails were real.

I heard @Leo mention this at some point recently, I think on the radio show. He said something about Bill wanting to shut it down for a while, because he was getting older (retirement implied) and using the pandemic as a reason.

Mentioned ages ago that he was going to stop, but appears to have kept going. I guess the current pandemic may have given him the impetus to stop; he won’t have to manually mail the cards as he was doing.
