Probaly my last price suggestion, since I seem inexperienced with this. Would love some feedback though! ^-^

One offer in 1 month. B/O at 280 keys. Got a 275 key (270 now) unusual offer. -> http://i.imgur.com/AGEFPmV.png - http://www.tf2outpost.com/trade/28818090

11 months outdated price, needs an update. -> http://i.imgur.com/SlYpIiP.png - http://backpack.tf/stats/Unusual/Human%20Cannonball/Tradable/Craftable/38

Both in existence are duped. 43+ days since last sale -> http://i.imgur.com/oZP7pwt.png - http://backpack.tf/premium/search?item=Human%20Cannonball&quality=5&tradable=1&craftable=1&australium=-1&particle=38&killstreak_tier=0

For sale at scrap.tf for 145 keys pure, been there for over 3 months. As that's almost half the price of what it is now. I think it really should be lowered. -> http://i.imgur.com/hSEXcNm.png - https://scrap.tf/unusuals/89

Extra: The Harvest Moon one, who is similar and often more desirable/rare got a huge drop. And only clean ones were in existence, I don't know. But I think that also brings up some reasons to give it a drop. (just an opinion, won't affect anything else. just something I wanted to add to it)

Final: 145 keys (since it's up for sale at 145 keys. and 145-270 isn't a reasonable range)

Let the games begin!
