Few selling for under 2.5 keys: http://backpack.tf/classifieds/search/cockfighter - Edit: Very first is a re -post.

Counter proof: (I think they're still in the range, as they're not pure key offers)

Offers 3 keys in items: http://www.tf2outpost.com/trade/9406373 (Quiet old)

Offer of more than 3 keys in items: http://www.tf2outpost.com/trade/9595277 (--> Just got accepted)

--> So because so many are unsold at 2.5 keys and some are willing to sell for 2 keys to quickbuyers, I think this price range would be better. As this is my first suggestion, I would liketo get some feedback.
