Agreeing here, the prices in unusuals reflect the price to be around that range, maybe 3 buds at most.

i think this hat should actually be a little higher than 3 buds, a searing plasma buccaneer's bicorne goes for 3 buds as well. there is only 2 on tf2op. I used to have searing plasma buccaneer's bicorne, and got some nice offers over 2.5

Why did you link to a trade with a Purple Energy Cowl?
