Conclusion: Dat price! I know. But is really hard do a range for this item. 0.9 Key includes 10.77 - 12 Refs, according with tf2calculator configured as 1 Key = 12.66 Refs. I should include 10 Refs to the range due the 8 classifieds sellers? Maybe, but there no are any seller on outpost for 10 refs, only 1 guy.
