I wasted... a lot of time on that game lol...depending on your level and professions, if you have herbalism you can make some good cash of of primal's (life, water, etc, etc. )
If you want to do it the old fashion way, go mining/skinning. The cat's eye you get from veins are worth a lot, and you get quite a few. Also, once you get to outland, you can get mote of fire off fel iron veins. they sell for a lot.
the problem with mining/skinning in outland is I would have to abandon my 365 tailoring/jewling. I spent way too much money getting those up to drop em. There's always alts, but leveling them just to make money...there's got to be an easier way. which is what I'm asking here. or if there's a site that you've used to buy gold let me know. lots of companies out there, but until someone tells me they've used it before I don't trust em.
