Gonna be really careful with this 2nd re-suggestion of my counter suggestion

Sales for 2 buds:

http://puu.sh/91Ynx.png (sold for stormy yellow belt worth 2.5 buds, ~2.3 buds after calculating overpay but the seller added sweets which was a tuxxy (3 ref) and 41 refined which adds up to 5.5 keys together (~0.3 buds)

2.3-0.3=2 buds

Credits to Pan on this sale xD

Mini suggestion for the circling tf logo trophy belt:

2.4*0.9=~2.2 buds as it sold for a vivid plasma fruit shoot (Refer to the links for 2.2 buds sale)
