A few rares (yellow) have been dropping for me recently, I've had maybe 3-4 in a couple of days while exploring casually, and I was wondering about people's Trading Post strategy in GW2. So far I've been salvaging blues, and have sold one or two masterwork pieces (greens) for a few silvers.
Now these yellows are things like a plate shoulder which is part of a lvl 42 set, and the lowest seller on the TP posted at 23 silver, while the highest buyer was looking to pay 11s. That's an interesting situation because for a really quick sale you can match the buyer, while for a higher profit you can undercut the lowest seller by an amount and it might take a while to sell...
What do other people do? At what point does it become worthwhile to TP stuff rather than salvaging and selling the mats? What kind of strategy do you folks use to set a price when posting something at an offered price, ie how often do you get a sale on something that's not buyer-matching?
