Gold

Hello,

What are the most profitable ways to generate gold in Icecrown realm?
I have maxed out Mining & JC.

I need to buy primordial saronites for the quest "the sacred and the corrupt".
I know i can get it from frost emblems too, but i want to get it via both emblems and money.

Flipping the AH. Everything else is a complete waste of time.

Thanks, but how can one flip the AH?
