None on OP?

http://www.tf2outpost.com/trade/21697156 ~ Sold for 3 buds and 5 keys = 3.2 buds at that time

http://www.tf2outpost.com/trade/21283957 ~ Sold for a towering pillar of shades = 3.5 * 0.9 = 3.2 buds at that point of time as the shades cost 3.5 buds at that time of trade

Trade was done on 26th, which shades were 3-4 buds.
