Price Range

There's only 4 of these hats around, and only 2 of them are on outpost. A third guy stopped trading, I guess: http://www.tf2outpost.com/user/48726 . The trades on outpost get offers of around 3 - 3.4 buds quite easily, but neither of the owners is caving in and selling for less than 4 buds pure.

Low end is 3.2 because there are plenty of buyers/offers at 3.2. As for the high end, because supply is so limited, I'm going to have to stretch out the high end to 3.7 because any buyer looking at this price suggestion would need to know what the two sellers are expecting. And you'd be hard-pressed to convince them to sell for 3.4.
