My 57 WWWWS group has about 170g each after buying their level 40 mounts. My 34 MMMMP group has about 15g each so far. I disenchanted all my greens on the warrior group up through about level 30 to level my enchanter and then just vendored everything for gold. Not doing any tradeskills on the casters yet, though I'm saving my cloth for additional tailors. I'm also extremely casual/lazy. I am also not grinding dungeons as I get bored pretty quickly. I'll run an instance usually about 5x at most to cover not having to do the more odious collection quests in a zone. (Uldaman is an exception due to the way quests in there are structured.)
