Hi,
I add copies whenever I sell a game either in digital or print formats, across itch, DriveThruRPG, shop.montfordtales.com, and convention sales (basically anywhere where I know a copy has been sold). They do disappear quickly when I add them, but folks are always welcome to email me for a complimentary copy code if they don't want to rely on the whims of the community copy pool. (FWIW, this also applies to The Almanac of Sanguine Paths, for which I note you've also left an identical post.)
I hope this helps :)
