To earn real money on WoW you can also using Heroes powerleveling. Such services can mainly be served in a normal store which has its own team created for powerleveling clients but you can also find individual players in the game (it's harder to find them and there is no guarantees).
Don't forget about making money on selling payment cards and keys –they are also in demand although the competition is very high too. While this option is the fastest for earnings (you have bought them for one price and have sold for higher one) but here you won't deal with it without your own store or account at plati. ru.
And in conclusion it's possible to earn at the Auctions. Everything is sold in the game from various potions and to rare ammunition. And while many deals are penny, some of them blow your imagination - who will buy virtual armor for a thousand euros. But somebody byes it…
