I'm still fairly new to WoW, and I'm currently trying to buy about 100k WoW gold left, and nobody is selling for my server. Is there a way to kind of manipulating it? I heard something about possibly buying pets and doing it that way?

Thanks in advance!

Buy pets and sell on the AH. Try checking the undermine journal fornprices. They fluctuate so you may not get what you want or you may get more. There are also fees with AH.
