I got a rogue with, Mining and Herbalism, he does all my dailys, while on dailys i mine and gather herbs.
My main is 375 Enchanting, so while waiting for raids ect, i make some gold enchanting. I did spend about 5000g to power level my enchanting though :S
With the Hallows eve stuff, i went around all the inns and collected all the candy, made about 250g doing that. Did a full BT clear made about 130g from that.
I don't pay for pots as i use marks of the illidari for it.
I've been lazy recently sitting on about 400g, i have about 400g worth of voids and large pri's in my bank. I've been getting uber cheap voids, and shattering them, I made 100g in 5mins doing that 2days ago.. Some people just put voids on for like 3g each to make some quick gold, then i sell large pri's for like 8/9g each
Currently leveling herbalism on my Warrior for the new boosts in WOTLK. But thats going slow atm, due to little time and lots of raiding atm.
