This video will hopefully help those of you frustrated by being unable to flip Exotic items on the Trading Post. I feel bad because I talked so much about fast flipping that most of you probably just tried to use the same strategy on Exotics... with tragic consequences.
Being successful with Exotics is all about competitiveness. You need to undercut harder, sell lower, and basically bloody your opponents through pricing. The one copper under/over cutting you're used to isn't going to work in the big leagues.
