Key offers (mostly by the same guy)

http://www.tf2outpost.com/trade/6568993 (Also has an offer of 1.5, but in the form of the Schadenfreude

http://www.tf2outpost.com/trade/6800116 (Actually 2 ref)

http://www.tf2outpost.com/trade/6714737

http://www.tf2outpost.com/trade/6624854 (A key AND a scrap!)

http://www.tf2outpost.com/trade/6598133 (One offer of 2 ref and another of a key, but not sure which one it sold for)

Conclusion: The amount unsold for above a key warrants a price drop. The fact that two 2 ref ones went under the radar is also pretty interesting.
