to buy things with coin NPC

I have a NPC in my flyff that sells things, but it is bought
with penya. I want that they buy themselves with coins that
I have created for my servant as I can put it?

You need to edit the Source. Look how it works with the RedChips and try to copy, paste it.

If you cant do this follow this 3 steps:

1. Spam many Threads with the title "help i cant do this".
2. Get many Infractions.
3. Get banned by Sedrika.
