The Private Store is a unique and highly valuable tool that Aion players need to get used to and ultimately master if they are going to develop the Kinah they need to be at the top of their game. There are a number of ways to go about doing this. However, the most important thing to remember is that without a centralized location as with an auction house or the Trade Broker, you must do a lot of the hard work in selling your goods and getting attention. If you can become a good merchant with highly desired products and good prices, you will be much more successful than most other merchants in the game.
Finding a good location for your Private Store is an absolute must. To start with, you need to choose a hotpot that will allow you to target very specific items that your customers will want. For example, if you set up shop outside of an instance, you can sell those particular players the alchemy and cooking items they need to run that instance. If you set up shop next to a quest NPC who requires a certain item, you can make a great profit from buying and reselling that item to those players. Just make sure wherever you set up shop is full of your ideal customers.
The Right Prices
If you meet a demand, you can usually ask for a larger profit from your items, but you will need to be careful not to gouge anyone out of their Kinah. Even if you get away with it, most players will eventually recognize they got a bad deal and make a point of not going back to you for further products. You want to develop a reputation for fair pricing, not opportunistic gouging.
How to Market
You can set a message for your store, but make sure it represents you and what you have to offer. Be specific and describe benefits players might get from dealing with you as opposed to other players. Additionally, make sure not to resort to badmouthing other players or to spamming the chat channels to draw attention. These things all fail to work more times than not.
Gaining Kinah in Aion is a multi-faceted process that starts and ends with a good Private Store. Set up in a good location with solid prices and a good marketing strategy and you will ultimately do very well for yourself, above and beyond what you might expect from your fellow players.
