This price needs an update. There aren't many with these on outpost, and most got offered 2.33 Ref, and some declined.

http://www.tf2outpost.com/trade/9264000 (made 5 days ago, not bumped once, still got offered 2 Ref several times and 2.33 Ref once.

http://www.tf2outpost.com/trade/9374484 (made 1 day ago, already got offered 2.33 Ref)

http://www.tf2outpost.com/trade/9394593(my trade, i sold it for 2.33 to someone who added me)

http://www.tf2outpost.com/trade/9398256 (made 14 hours ago, sold almost instantly for 2 Ref)

http://www.tf2outpost.com/trade/9386490 (made 1 day ago, asking for a Key, kinda ridiculous)

http://www.tf2outpost.com/trade/9398236( selling for 2.33 Ref, opened for 18 hours

Buyer trades:

http://www.tf2outpost.com/trade/9215903 (buying for 2 Ref, kinda irrelevant cause he didn't bump it in a week)

http://www.tf2outpost.com/trade/9179418 (quickbuy for 1.66 Ref, doesnt seem to be successful)

http://www.tf2outpost.com/trade/9410518 (quckbuy for 1.66)

http://www.tf2outpost.com/trade/9401377( quickbuy for 1.66)

The quickbuys don't really affect the price. People get offered more than 2 Ref, so the price should reflect that.

EDIT: Although it says that i own one, I made sure to sell it before i opened this suggestion, so I don't try to raise the value of my own items.
