I'm laughing so hard at the guy that thinks that he can get a Smissmas Caribou for this.

Only two useable sales in the last 3 months.

Sold for a Strange Festive Pro KS Wrench(14 + 14 = 28)(25 Keys with Overpay)

Sold for 31 Keys

The average comes out at $33.41(Roughly 14 Keys)

Using keys because both sales were basically in keys(SCM Price estimations are always in keys, not in buds, and a pure key sale.)

Two sales, 25-31 Keys should be fine.

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