I saved up enough coming into the expansion that I had my major expenses out of the way. I had already bought my master flying the first day it was available (screw you, Blizz, for lowering the cost by a grand a week after I bought it). And I still had a good chunk of cash going into the expansion. I'm now only one zone away and only about 40 quests away from having loremaster of cataclysm done, and that was a good chunk of money I'd saved from vendoring quest rewards.
I've also gotten my JC up high enough to start selling a cut blue gem on the AH and made some nice cash before quite a few others people now have the +60 stam gem.
Titansteel is also ridiculously cheep right now. I snagged 12 bars and two arctic furs for about 500 gold, and then went farming for 80 bars of cobalt. And I went back to questing for a while until I had over 12500 gold, and contacted a guild engineer and HAD MY VERY OWN CHOPPER MADE!
Yeah, yeah ground mounts are mostly useless now - but shut up! Yer just jealous.
So I go back to questing to remake some money to pay for repairs and the like when lo-and-behold I looted an 85 BOE epic. My jaw dropped - and sunk even lower when I saw the going rate for BOE epics on the AH.
I netted myself a cool 18,500 gold and promptly bought a travelers tundra mammoth too!
And after questing a bit more, I'm back up to roughly 3500 gold again!
And I hit a nice milestone too - Cataclysmically Superior!
What an awesome weekend. I'm still in disbelief.
