- The Rare Orchids Order can be taken from any post office (as a poster on a wall, similar to a Wanted poster; not as a piece of mail) after completing the stranger mission. The player must take the note before saving and loading the game in the next time because if the player saves and loads the game before taking the note, the note will disappear after loading for unknown reasons. At the Saint Denis post office, it is posted outside, next to one of the side entrances.
