Before anyone counterproves

http://www.tf2outpost.com/trade/21710569 - did not sell for 1,44 as listed ([url]http://www.trade.tf/trade/486534066[/url]) - current owner relisted it for 1.33 ([url]http://www.tf2outpost.com/trade/21713063[/url]) which would be senseless if they bought it for more

http://www.tf2outpost.com/trade/21669661 - did not sell for 1.66 either, it was relisted on http://www.tf2outpost.com/trade/21706196 for "backpack prices" which ultimately sold for 1.33 ([url]http://www.tf2outpost.com/trade/21709268[/url])
