4 months old price, definitely needs a drop.

Sold for smoking TC (~4.6 buds)

http://www.tf2outpost.com/trade/11408019

Was "quickselling" for 4 buds

"Quicksale" for 5 buds (1 week unsold)

Was "quickselling" for 4.5 buds

Tried to sell for 6 buds unsuccessfully, had highest C/O of 4 buds, or lantren snaggle + 10 keys (~4.8 total).

Conclusion :

5.7 buds is totally outdated price, too many people try to quicksell their hats at 4-5 buds unsuccessfully. It doesn't looks like they got any good C/O's either. One of them finally sold for a smoking TC (~4.6).
