That's why you need two wow gold accounts.
When you both play a high level character which can earn lots of wow gold in one day and a low characer in the opposite faction which is very poor, you want to transfer your wow gold from high level to low level, While unlucky, there is no easy way to transfer wow gold from one faction to another. Don't worry, i only mean no easy way, there is still a way to help you do so, i show you in this passage.
To transfer money between Alliance and Horde, you should have two wow gold acounts at first, because wow gold players cannot bid on their own auctions even if they're on different characters within the same account. The neutral auction houses at Gadgetzan and Booty Bay are where all inter-faction WoW gold transfers take place. So your low level character should go to the Gadgetzan and Booty Bay first.From Orgrimmar, the player should walk to Crossroads and then east to Ratchet. Ratchet has a boat dock where a ship can carry characters to Booty Bay's neutral auction house. While from Thunder Bluff, it's a long walk to Crossroads, but there should be no problems with the level 20 mobs if one sticks to the road. Flying directly from Thunder Bluff to Ratchet is an option as well. From Undercity, the player should take the blimp to Orgrimmar and then use the Orgrimmar instructions above for the rest of the journey to Booty Bay.Reaching Booty Bay requires walking through Horde territory so it is a very difficult to transfer wow gold. On PVP realms, there is a high likelihood of getting ganked along the way. From Darnassus, it's a very long walk through Darkshore and Ashenvale before going south through Horde territory in the Barrens. If possible, players should fly to Astranaar from Auberdine to save time from walking through Darkshore. Once the Alliance toon reaches Ashenvale, he is subject to being ganked at any point thereafter on a PVP realm. The Alliance character can't enter the Crossroads when reaching the Barrens, just go east towards Ratchet to take the boat to Booty Bay. If the Alliance toon enters Crossroads, he will be killed on sight by other players or the Horde guards at Crossroads.As soon as the low level player arrives at neutral AH, the first thing he should so is to post a worthless white or gray item for the amount of wow gold he needs in the AH. When transfer wow gold, the player's high level charecter needs to get another wow gold account to go to Booty Bay or Gadgetzan, and buy the item the lower level character posts. The in-game mail system will send the proceeds to the low level character for the successful auction. That's why you need two wow gold accounts.
