Just a quick tip here. I like to remain cost effective cos I'm tight :P

I'm hoarding herbs for a bit of price gouging come Wrath, and I've set up herb mule alts on various realms to do this. Instead of investing 10s or even 100s of gold in bank slots and expensive bags each alt gets only 2g sent to him. This 2g is enough to buy bank slots 2 and 3 (1g10), and 6 12 slot herb bags (from your friendly local herbalism shop), if you have the character slots free, this can be a very cost effective storage solution.

its sort of unfair that you can get such great value herb bags compared to other professions, enchanting, engineering, mining and gem bags are more expensive and are not so readily available for an L1 alt.
