http://www.tf2outpost.com/trade/27051703 - bought for 5 ref

http://www.tf2outpost.com/trade/27058487 - buyer for 5 ref

http://www.tf2outpost.com/trade/27058487 - buyer for 4.66 ref (same classifieds buyer for bp.tf 5.33 listing, so confoose)

http://www.tf2outpost.com/trade/26988065 - has sold some for 9.66 ref (seems high -> outlier, not using, but supports hype)

http://www.tf2outpost.com/trade/27059639 - seller for 4.22 ref (seeing as though there're higher buyers, not using this)

Others are too low and seem like outliers, NOT USING.

Conclusion:

The buyers for this raised from 4-4.33 to 5-5.33 in less than a day, I think it's safe to say that this is raising a fair bit thanks to Invasion hype, so taking range of 5-5.33.

Let me know if anything's wrong~
