Sale #1: http://gyazo.com/1ec08852a362c961c4c8962a77f7a7db http://backpack.tf/item/489985192 No mini needed for marauder. Marauder = 38 keys. 38*0.9 =34.2 round down to 34. Other sweets were added, Team Spirit Juju = 5 keys. Keys were around 19 refined during this purchase, the three genuines added up together = 18.77, rounding up to a key flat. Also appears that a strange shotgun and another one key genuine were added, With this being said the total would be 7 keys and 12 refined, Which i'm going to round up to a key? 8*0.9= 7.2, rounding down to 7. 7+34= 41 flat.

Thank you Aaron for assisting me with this.

Sale #2: http://gyazo.com/bd88e142d2b07afaa2a47471e2f2387a 1:1 with a sf scatter. http://backpack.tf/item/636513052

Edit: Did further digging. SF Scatter was worth 25 keys at the time of purchase. However, this sale is an outlier. http://www.tf2outpost.com/trade/25533967 Proves that it had much higher offers than the scatter (Thank you Leo ;[)
