Just looked at the Outpost for a Skull, while having the backpack.tf Price in mind, realizing there are a few cheaper ones then the actual price over here.

Here are some trades: http://www.tf2outpost.com/trade/9368384 http://www.tf2outpost.com/trade/9301098

http://www.tf2outpost.com/trade/9370564 (If you take away 2 keys because It is painted Black)

And that other trade site: http://tf2tp.com/trade.php?trade=9249186 (Also substract at least 1 key here, since it is After Eight)

If you disagree, just write a comment below, I'm happy about any feedback :D
