Ok, this works best on a pvp server since you can't have horde and alliance on the same account thus a lot less trading between horde and alliance. What I did was had a buddy from college roll a lvl 1 on my server as horde that I had my 70 alliance on. We then went to the auction house and saw that the patterns from SSC for boots were selling for around 90g on horde side since they have progressed a lot further than our alliance side. Those same patterns sell for around 400g alliance side. So all you do after that is the old neutral AH switchero and you can make a bunch of gold in one sitting. It's also amazing for being on the same server, how much of a price difference there is on a bunch of items. Hope this helps some people.
