Stormy Storm Dragonborn Helmet

I do not like and I am against the price that was adopted here http://backpack.tf/vote/id/513d407b4bd7b8192d000006 , because :

1.Here, he has not shown sold hats(how can we talk about the price of a hat without knowing for how much it is sold or bought?),only offers.

2.He did not find best offers.

3.The difference between the price range(0.1 buds) is very small.
