#1 - Tavish DeGroot Experience: http://backpack.tf/item/3537417864

Seller: http://backpack.tf/profiles/76561198085116555?time=1423858338

Buyer: http://backpack.tf/profiles/76561198082830143?time=1423885937

Sold for a Circling Heart Demoman's Fro ( http://backpack.tf/item/353321766 ), a Strange Festive Grenade Launcher ( http://backpack.tf/item/1334364611 ) and a Strange Specialized Killstreak Festive Stickybomb Launcher ( http://backpack.tf/item/617564709 )

Grenade: 5.6/12 = 0.46 (0.5). 0.5*0.9 = 0.45

Stickybomb: (13+1.25+0.29+0.26)/12 = 1.23

Demoman's Fro: 4*0.9 = 3.6

So; 0.45+1.23+3.6 = 5.28 (Rounded to 5.3 buds)

Buds were 12 keys: http://backpack.tf/vote/id/54dbfe63b98d8841718b4706
