Ok, 3rd times the one :D

Thank you very much to Ruktfist for helping with calculating overpay and coming up with the range.

Proof:

Sales:

http://backpack.tf/vote/id/5266be1e4cd7b8d82e8b4568 (Luminous sold for a N&B executioner; 2.2 buds.

It seems that he never listed the festivizer on tf2outpost, BUT I was able to find a trade proving he had a n&b executioner in the same time-frame- http://www.tf2outpost.com/trade/14659382 )

http://www.tf2outpost.com/trade/14356692 (sold for a green black hole steely toe; 2.3 buds at the time)(Bossbob did actually buy it, as he is listed as the next owner)

Overpay

N&B Executioner overpay: http://backpack.tf/stats/921/5/31 Original value is 1.7-2.2 buds so either 1.7 buds or 2 x 0.9 = 1.8 buds

Green Black Hole Steel Toe overpay: http://backpack.tf/stats/481/5/71 Original value is 2.3 buds so only x0.9 method can be used here. It's 2.1 buds when rounded.

A range of 1.8 - 2.1 buds seems appropriate.
