Sold for a Miami Nights Officer's Ushanka(1.4 with Overpay, Outlier)

http://www.tf2outpost.com/trade/21740792

1.4 Is way too low for this(Considering one has a C/O of 2 Buds and 8 Keys, and got offered 40 Keys: http://www.tf2outpost.com/trade/21035545 )

3.1-3.2 should be fine.

Additional Proof/Counter-Proof/Constructive Criticism/Feedback is always appreciated.
