I make 3k a day minimum from selling fools cap on my server, and its only about 20-30 stacks at a time. Ive been using all of my Ghost iron ore to make bars which I then transmute into Trillium bars because they cost about the same. I've also made a lot of money off of selling fish, blacksmithing weapons (463 crafted ones), 4 476 BOE world drop epics (just got a 5th today), as well as selling off old herbs and ore that I farmed in excess for leveling up 4 extra alchemists + 1-2 scribes.
So far I've made over 5 DMF decks, 3 of which ive given away to guildies (because I am GM of a raiding guild). And two others I'm trying to decide what to do with...If it werent for the fact that I have a bad habbit of buying my GF gifts in game I'd probably have over 200k (after dumping 90k at the start for quick profession pwrlvling and tank gear crafting to use in raids).
I know it isn't much but there is plenty of money to be made if you know what you are doing. I'm no expert by any means, I wish I knew better ways to make lots of money. But with two accounts I can bot all I need and then some!
