Tam O' Shanter Mini Suggestion

http://www.tf2outpost.com/trade/19868968 1 Month unsold at 17 Keys

http://www.tf2outpost.com/trade/20535733 1 Week unsold at 13 Keys, no offers

http://www.tf2outpost.com/trade/20785367 Young, 15 Keys

http://www.tf2outpost.com/trade/20744704 Young, 14 Keys

http://www.tf2outpost.com/trade/20651164 4 Days unsold at 15 Keys, no offers

Pricing it at 13 Keys, merely because of the 1 week unsold without offers and that young 14 Key seller(Leaving it at 12 Keys with overpay, Outlier)

Stout Shako Mini Suggestion

http://www.tf2outpost.com/trade/20125162 Got offered 1 Bud

http://www.tf2outpost.com/trade/20741996 Selling for 18 Keys, young

http://www.tf2outpost.com/trade/19002248 2 Month unsold, got offered 1 Bud several times. Also has several offers around 1.1-1.3.

Going to price it at 18 Keys, because the 18 Key seller is the only one with a B/O. And most offers are around this price(16 Keys with Overpay)

14 is reasonable, especially because of that Tam O' Shanter outlier. 18 Also seems to happen though.

Additional Proof/Counter-Proof/Feedback/Constructive Criticism is always appreciated.
