Aion trading features is unique and special. Like most of MMORPGs, Aion allows players trading items for Aion Kinah between players, selling items to NPCs and so on. Acknowledge these features to enrich and enhance your Aion life.
How to trade between players? In Aion, Trade between players can be initiated three ways:
You can right-click on a player, and select "Trade". Or you can click on the Target Status Bar, and select "Trade". You can also target the player, then type "/trade" in the chat window.
If you want to Sell items to NPCs, make sure you make the largest amount of Aion Kinah from them. Vendors will buy items back from you at set market prices. This is a great way to purge your inventory of unwanted or un-needed items. You can even get rid of most of the junk simply by clicking on the Sell all misc button. After all, one man's trash is another man's treasure. However, you may wish to watch the Trade Broker, and see if you are able to find ways to make more Aion Kinah through auctioning off some items.
It's very simple to sell items, drag them from your Inventory into the shop. The accumulated amount of Aion Kinah you will receive shows up under Total. Click on Sell once you have decided on all the items you want to sell, and then click Close when you are done.
Put your items up for consignment at a Trade Broker to make more Aion Kinah, if selling your items off to NPCs is not making you the Aion online Kinah you think it should. Items are added into the lists where other players can sort through and shop for what they want. When you sell something through a Trade Broker, it will cost you a small fee of Aion gold proportionate to the sale price you are seeking.
Also you can open up your own Private Store and sell items for whatever price you like to make the amount of Aion Kinah you wish. The upside is that you can be your own boss, and enjoy the successes and failures of your own entrepreneurship. The downside is that you will have to be online (and not doing anything else) during this process, so you are trading solid gameplay time to tend to your store.
