Pretty old price, in need of an update in my opinion

Last month I bought one for 8 buds and a Professional Killstreak Collector's Original (buds were ~16 keys at the time and everyone on Outpost wanted 20+ keys so let's call it a bud) - http://i.imgur.com/sIuFzdE.png

I sold that Reggaelator for a Burning Hallmark ( 12.3 x 0.9 = 11.07 ) - http://i.imgur.com/0ewU69t.png

I bought it back today for a Burning Glengarry Bonnet, a Max Head, and 2 buds ( 5.5 x 0.9 = 4.95 + 5 = ~10 ) - http://i.imgur.com/emzVoYv.png

Another sold for 11 pure and had an offer of a Burning Phantom, 1 bud, and a Big Kill (~ 10.5) - http://www.tf2outpost.com/trade/20889129

Additional proofs:

http://www.tf2outpost.com/trade/21278454 - B/O - 11 buds

http://www.tf2outpost.com/trade/20973254 - B/O - 12 buds

http://www.tf2outpost.com/trade/21418626 - looking for at least 12

http://www.tf2outpost.com/trade/18821474 - B/O - 15 buds

Any tips/additional proof would be appreciated
