http://www.tf2outpost.com/trade/6104474 From item history you can see it went to ๖ۣۜHellg̛͕̖a̳͓͍̰̟̭̻̼, in this trade http://www.tf2outpost.com/trade/6254241 you can see the Max and Buds were previously owned by him, confirming that this was the trade (of course not with 100% sure if sweets were involved in either side)

http://www.tf2outpost.com/trade/5898772 this one passes by nastya triplemeow but ends up with CªpτªιиMªяνәḺØυѕ, who previously had these 3 Buds in his possesion http://www.tf2outpost.com/trade/5950117, so you can see the trade was the 3 Buds for the Jefe (again, not 100% sure if sweets were involved)

http://www.tf2outpost.com/trade/3746763 This is slightly old, but the Bubbling Cannonball offer is still priced at an average of ~3 (you can see by item history this was the offer the guy took)

One of the current owners bought his for 3 Buds http://www.tf2outpost.com/trade/2982580 from this guy http://www.tf2outpost.com/trade/2854638
