I have been selling parchment for a while. I mentioned it once and I saw where the Greedy Goblin started to do the same. For a while he posted pictured of idiots buying them that people sent in and he finally had to tell people to stop sending them. I started to sell other items that all the vendors sell.
I can understand some of them that people buy, they just don't know a vendor sells it. How many people can honestly say they do not know rune thread is a vendor item. This guy wanted them so bad that he picked up 2 of them.
I am kind of speechless.
Update: I just checked another character and saw this. Same guy picked up a 3rd one.
