Been playing in Skal for a while and it looks like the permanent shops in Skal do not go into bidding once they are released. Looks like once they are released they go into a status where anyone who's lucky enough (or metagamed) can grab them. That's actually prety bad considering how much money those shops can make, specially the ones in the Trade Post, and how much the system can be abused by metagaming releasing it to a friend.
Well, that's it.
