Consider my post a bump too.
I haven't heard anything from them (or anyone who's purchased from them recently), but they should still be in operation. As I understand it, though, the owner is focusing on their Coral Farmers Market business rather than their Reef Farmers business right now. The CFM FB page is updating regularly, and the RF FB page hasn't updated since 2020. They'll probably get back to you eventually, but it seems to be a relatively small operation, and there doesn't seem to be a huge demand for it, so I'd imagine they probably don't check their inbox very often these days.
