Economy

Buying
The buyer must be satisfied with the seller's price, if not, the buyer will get discouraged and find something else to spend their gold on. Of course, you can't satisfy every customer, so some will end up like that, and there's nothing you can do but move on.

Selling
First, the seller has to find a reasonable price for an item, and that depends on the situation. If your're selling rubies and everyone else is, you need to sell your item for the lowest price. If your're selling an item that is very uncommon to see, you need to price it higher, but not too high.

Transporting
Some dragons will ask you to transport their order to their home and tell you where you live, so it's advised you come with a friend so if the buyer asks for a transport, one will go, and one will keep selling, and until they get back, you can put up a no transport sign. Or, you can just put up a sign that says no transportation.

Supply and Demand
Supply and Demand is where if the seller is willing to sell a item for a certain price, and if the buyer is willing buy that item for that price. If the buyer pays less than willing to, and the buyer got more than they expected, this is called a surplus, and both the buyer ans seller will adjust or not adjust their prices willing to buy and sell, and they will both come back the next day if they have a surplus.

Long Tails
Long Tails are scenarios where a product suddenly decreases in popularity, and is every seller's nightmare. It will most likely happen when a product has been sold so much, fewer and fewer dragons need it. It can also happen when hundreds of sellers place their prices too high, and the buyers end up ignoring most of the dragons selling that product.

Other Info
A store must be unique from any others. For example, let's say you're a Sky Dragon, selling gold, but many other Sky Dragons are selling them. You have 2 options, set you're gold to the lowest price, or change your item to a different one that little to no people are selling, like diamonds. Feel free to ask any questions you have.
