Buyers less than 2.33

http://www.tf2outpost.com/trade/10741054 (At Least 4 People willing to sell for 2 Ref)

http://www.tf2outpost.com/trade/14344697 (Instant Buy for 2.22)

In Conclusion, due to the amount of people selling it (which is extremely high) and for the demand of it (which is extremely low), it is very reasonable to lower it. It is a not bad misc., but i guess it is getting a bit too old for people (no pun intended).

Side note: Yes, I went through every trade available in tf2oupost whether bumped or not consisting the brainiac hairpiece. My proofs only consists the ones that are at most valid. This is to stable the misc entirely, but more in mind comes to show that the price will soon decrease.

Low Demand+So many to sell=Lower pricing.
