Yeah, but there's not much demand for those items... when was the last time you saw someone using a QS timer?
They're just not that desireable. And added onto that, because they're not desireable, there's not market for them, so you can't really even sell them for TC... and even if you could, you shouldn't expect more than half of shop price, unless it's a hot item like Void or Azurite.
So in effect, you're offering 15k in items for an item that costs 42k in the shop, but is sold out and goes in the forums for 50-100k...
That's all tiebasher is trying to say.
