Buying an item. On kill mob announcement.

[Eridonis]

Two questions:

1) How to create a message when buying an item so people wont do a mistake of buying the same item twice with the Shop. 
2) An announcement of when the boss monster is slayed by a specific character. It announces who killed it.

1. Source code I assume

2. Global event on  NPC death: Chatbox message: \pn killed boss! (Not sure if it's \pn or some other command)

So there is no way to just put item successfully bought when buying an item from an item shop?
