Next outdated sunbeams price. 1 on op, but just look at offers:

http://www.tf2outpost.com/trade/9511115

B/O - 3.5

Offers:

~Blizzardy Bonk Boy (3.4-3.8)

~Hearts Whoopie Cap + lucky 42(btw whoopie is lowballed, p.energy whoopie is 4.3 buds and hearts are 2.3? http://www.tf2outpost.com/trade/10398332 - offer of 3.5+ buds in unu) so that offer would be 3.5+7 keys = ~3.7 buds

~Purple Energy Stuntman = 2.1-2.6 buds

To sum up: this hat had not just 1, but 2 offers worth more than 3 buds. I will add unusual overpay and set low and high end according to that. I counted unusual offer as 90%.
