Problem/Bug [SOLVED]Having problems with HyperConomy

I have a new server and I decided that I'd make some NPC shops
First
How to change the prices of the items in the shop
And if its possible to set the quantity of items sold to unlimited like a sign shop does.

Second
I don't know what this is but when I try to buy and sell items from my NPC. It doesn't add or remove any balance from me even though it said I sold an item for $100
my balance remains $0
I check /balance but my money didn't change
I did /audit and I saw the Theoretical balance increases but not my true balance.

Third
I did /baltop and Hyperconomy is #1 on list and my NPC's were included in the list as well.
How do I make it so hyperconomy and the NPC's don't show up in /balancetop and only the players would.

I have Citizen2, Vault, Hyperconomy, Hypermerchant installed



-EDIT

SOLVED
Switched to dtlTraders plugin. much more easy to setup.
Baltop problem. Hyperconomy and some NPC were listed in Userdata folder inside Essentials so I deleted them and they are now gone in Baltop list.
