Hello, it's been a really long time since I last contributed so I decided to give you a tip on how to make some very easy gold.
We all know that in 4.1 we some new pets were added, including the Winterspring Cub - Item - World of Warcraft which is sold by a vendor in Everlook, Winterspring Michelle De Rum - NPC - World of Warcraft.
Well, the interesting part about this pet is that so far not so many people know it is sold by a vendor and most Horde players think it is a pet obtainable only by the Alliance.
So all you have to do is buy it from the vendor(if you are a goblin and you have the Bartering guild perk you will buy it even cheaper) and then put it on the Neutral AH from around 300-500 gold. Given the fact that people don't know the faction the player who posted the item, this works for both Alliance and Horde and they sell very fast.
I made around 3k by selling these in just a few days and with so little effort
Good luck making gold.
