AUCTION HOUSE BASICS 101
This is an Introduction to the Auction House Basics 101, it is very important that you read this as I will guide you on how to use the Auction House properly with respect and effectively so you can earn gil and help the economy stay in good shape.
Ok so now up to this point you should be ready to use the Auction House. There are a few tricks to selling items but always remember that no matter how tight or desperate you are patience is the key to success.
When placing items up for Sale, check the price of the previous sellers.
OBSERVING SALES HISTORY
Example
FIRE CRYSTAL
11/15/13 Hexakai -> Leo 5,000G
11/15/13 Hexakai -> Leo 5,000G
11/16/13 Hexakai -> Leo 5,000G
Notice that on the 15th 2 stack of Fire Crystals sold while on the 16th, only 1 stack sold.
This is how you can see if the item you are selling is in demand or not.
Now lets look at another example.
Example
SILK THREAD
09/24/13 Hexakai -> Leo 5,000G
10/07/13 Hexakai -> Leo 5,000G
10/27/13 Hexakai -> Leo 5,000G
11/19/13 Hexakai -> Leo 5,000G
Notice only 1 stack of Silk Thread sold 09/24, 10/07, 10/27 and finally 11/19? That means this item does not sell often.
Now I'm going to explain how to put items up in Auction.
SELLING YOUR GOODS
When placing your goods in Auction House observe the price of the last sale. Lets say the previous person sold 1 Stack of Fire Crystals for 5,000 Gil. You can place your stack up for these prices:
Example
FIRE CRYSTAL
You could put 4,951G or 4,551G
Try not to outrageously discount your items. If you discount too much this will result in dropping the value of the item you have placed. Remember the purpose for selling items is to make gil for your hard work and effort.
If you wait patiently, your items will sell as long as someone else doesn't devalue the price out of self gain and greed.
A selfish person only cares about selling their goods as fast as possible regardless if they are devaluing the cost which can lead to competition between others. Also this could discourage people to farm these items which may lead to not having them available anymore when needed.
RAISING THE ECONOMY
Now I will explain how you can help raise the economy.
Example
MIST SILK CAPE
11/24/13 Hexakai -> Leo 12,000G
11/25/13 Hexakai -> Leo 13,500G
11/26/13 Hexakai -> Leo 15,000G
11/26/13 Hexakai -> Leo 15,000G
Say you are selling a rare item like Mist Silk Cape. Auction shows that one sold on the 24th, 25th and two sold on the 26th. But no one currently has a cape up for sale. This would be the perfect opportunity for you to put the cape up for a higher price say 16,000G instead of 15,000G. Not only would you make 1K extra, you also helped raise the value of the item.
NOTE: Usually it's best to place your items up in Auction before you log out. Or if you plan to do something time consuming and can check up on your sales later.
