only thing that ticks me off is when you low balled a already low price.
for example ill sell Hawk Set piece for 30k it cost 35k-39k in guild stores and I get offered 20k for it? No thanks I could sell it for 35k if I wanted to be a jerk.
On the flip side, when someone is trying to swindle new players out of money in their WTS's (Breton Motif 2.5k..... Lol) I go out of my way to publicly make sure people know thats a crappy sky-high price. I've seen others go out of their way to do the same, and it makes my heart all warm and fuzzy.
I publicly blast whoever is trying to make a ridiculous high sale on a item if they are spamming it in Zone Chat. Ive also seen 3 people constantly undercutting each other, to which the guy with the lower price told the other 2 "Suck it"
Vampire bites. Every time I see someone selling one for thousands, I offer mine for free to counter them.
I don't mind when people don't automatically include price for x in their advertisments.
I do mind is when I ask them how much they want to x they respond with "offer".
So I lowball them.
Then they get mad and say "but x is worth"
And then I say, well I did ask you what price you wanted....
