Only 7 on outpost, 2 aren't actually selling, 2 are selling as a set.

http://www.tf2outpost.com/trade/8454591 Had an offer of 4.33, sold.

http://www.tf2outpost.com/trade/8476940 Never bumped, selling at 4 ref, and me as a willing buyer :p

http://www.tf2outpost.com/trade/7912945 Selling as a set, but has an offer of 2 ref + 2 hats worth 2 ref (~4 ref)

http://www.tf2outpost.com/trade/7851786 4.88 offer, others of 4.33

http://www.tf2outpost.com/trade/8460328 Only bumped one day, has offer of 1 key + 1.33 ref (~5 ref, but the guy who posted it thinks keys are 3 ref still)

NOW FOR THE BUYERS:

http://www.tf2outpost.com/trade/8547685 New trade, buying at a key.

http://www.tf2outpost.com/trade/8430816 Unsuccessful for 5 days with autobump at 1 key

http://www.tf2outpost.com/trade/8531177 Buying at 4 ref, still new.

Tons of people quickbuying under 3 ref, a few at 3 ref, all unsuccessful

CONCLUSION: VERY hard to find, and with 1.5 pages of buyers and only 3 actual sellers, offers are getting higher.

And if you steal that 4 ref one from me, I will hunt you down. >:C
