http://www.tf2outpost.com/trade/12250497 - Offer of a Lantern Stash (5.1 buds), sold for Phos Metal Slug + Eerie Tree (4.1 + 2.7 = 6.8 buds)

http://www.tf2outpost.com/trade/11778064 - Offer of 4 buds, sold for Roboactive Cosa Nostra (~4 buds [ http://www.tf2outpost.com/trade/12149298 sold for an Anti-Freeze Electric Escorte which is 4 buds with overpay]) NB: due to Cosa being unpriced, this sale's "value" is sketchy and I'll consider it an outlier.

http://www.tf2outpost.com/trade/11578066 - Sold for Vivid Anger + unknown sweets (4.8+ buds)

http://www.tf2outpost.com/trade/11436006 - Offer of 5 buds, Sold for (this one's difficult) N & B Braniac + sweets + 18 keys (NB: judging by the response of another user, the sweets were worth ~0.5 buds) (4.8 + 0.5 + 0.8 = 6.1 buds)

Min value is 5.1 as most decent offers lie above this and I believe that at least 0.3 buds worth of sweets were added to the Vivid Anger. Max value is the highest sale.
