Pretending you're winning before it was mainstream.

http://www.tf2outpost.com/trade/23744302 ~ Sold for Aces High Full Metal Drill Hat but B/O of Drill Hat was 20 keys in http://www.tf2outpost.com/trade/23652731 making it 1.3 buds at that point of time for the Drill Hat so 1.3 * 0.9 = 1.2 buds

http://www.tf2outpost.com/trade/23769567 ~ Sold for a DP Prancer's but it seems that Headset was offered as it has a higher B/O as shown in http://www.tf2outpost.com/trade/23749328 making this sale 0.9 buds

Feel free to counter or support my proofs.
