NOTE: Overpay in unusuals is factored in my calculations. Best offers are typed in bold font.

I use the conversion at the time of offer (Using TF2Finance as a guide), as the value of buds has been really unstable in the recent weeks. (I.e. 1 Bud = 27 keys just a month ago, and 1 bud = 22 keys today. So offers of 1 pure last month isn't of the same value as offers of 1 pure today.)
