WoW TBC Classic Gold is a common currency in TBC Classic. Players can use Gold to get the gear, medicine, mounts, etc. they want. Players can also get WoW TBC Gold by selling things, many players will go to the auction house, and kill monsters to get it.
But when the player needs a lot of TBC Classic Gold, it seems that it is not a good way to polish it by yourself, because it is very slow and consumes your own energy. All WoW players buy TBC Classic Gold directly from professional websites, I am one of them, and I often buy it at MMOSO.com and MMOTBC.com. Just because the price is cheap, there are no security problems many times.
