You can build a reputation here and then use something like https://magicwebstore.xyz/ :)

You can put it in your bio and/or post about it.

We've mentioned that there will probably be a market sub at some point but I am not sure if it will be more than just external links.

I know it's convenient, but don't flock to centralized services like SN for everything. Using SN as a marketplace would be a ticking timebomb, imo

Maybe I should lead by example and sell something myself this way.

Just not sure what I should sell, lol
