Gold making technique is one of the highest competition field in WoW, thousands of players are trying to improve their gold making techniques everyday by researching and testing new methods. I have seen guides that promise 250g per hour, 500g+ per hour, 600g per hour. The number of gold per hour that keep increasing shows that there are always better ways in gold making.

As the title said, WoW Auction Mastery by Mayley Winter will show you how to make gold using the Auction House. It is not so special as any other guides already did the same, but a video she included shows that this is no ordinary Auction House guide: she create a new character, do some quests and sell her armor. With only 4 silver and 1 copper, she make 1000g in Auction House at only level 5. The whole process starting from level 1 until she gain 1000g only take 4 hours, and she did that without hacks, cheat, or any outside helps. You can see the video here: WoW Auction Mastery. As if it is not enough, Mayley also claims that she has over than 1 million gold scattered in different realms she played.

The other Mayley's free-and-must-see-video is 3000g in 20mins where she shows her typical activities in the Auction House and create 3000g just by being busy at the Auction House for 20 minutes.
