Today Bliz introduced the Pet Store for World of Warcraft, a new way for players to obtain in-game pets to join them on their adventures in Azeroth. Two brand-new companions are now available for purchase exclusively at the Pet Store in the online Blizzard Store: Lil’ K.T. and the Pandaren Monk.
1. Purchase pet
2. Get Code
3. Sell Code in Trade
4. Profit...
Pretty easy way of basically buying gold with out being banned! If not abused by scammers of course.
