One of the easiest ways to make gold in World of Warcraft is by selling limited supply items that other players really need. You need to go to certain locations, find special vendors, buy the rare recipes, essences, items, etc. and then run to the auction house and sell them for a profit.
Usually, when talking to a vendor, you’ll see a (1) or (2) next to rare items. This means there are only one or two of that particular item left for the time being. Sometimes, you can buy what’s left and sell it at the auction house for a profit. And, if you have time, you can stick around and wait a few minutes for the items to respawn and buy some more from the vendor!
Some limited supply items in World of Warcraft are worth more than others. It all depends on how crowded your server is and how much in-demand that particular item really is. Here’s a list of some of the special vendors you can visit to find certain items that will sell for a lot of gold:
