@weebdeluxe As a manga pub in the german speaking countries you surely should take part in atleast some bigger cons. Maybe dokomi, Frankfurt Book Fair or some stuff in Austria?
I mean I get this stuff is all expensive and other micro-pubs do also really only post on social media. But maybe those are more fiscally responsible? I dunno. Tbh I did not read to much up on the whole thing I will refrain from definitive statements
