Making Gold: Darkmoon Faire
##NOLIGHTBOX##Wow I didn’t know about these buggers!
You can read the entire story on Wowinsider, but here’s what it’s all about.
Lhara and Professor Thaddeus Paleo are selling gems, motes, herbs, potions and leather for pretty low prices. It’s on limited supply like Khorium Power Cores, but these are on a much faster respawn - if Wowhead comments are right, 20ish minute respawn could easily yield about 1000 gold per day, assuming you stand there camping for 5-6 hours.
You can check the official calendar to see when Darkmoon Faire is coming. They are scheduled to appear in Mulgore January 8 - January 14, so be sure to check them out. Good luck!
