Only 7 buyers on tf2outpost with 2 who not buying at the moment

Others are quibuyers (buying for less than 4 ref )

my experience for genuine quackenbirdt was i try to sold one for 5 ref during 2 weeks without success (when i started, it was at 1 key on backpack.tf). in the end, i trade it for a genuine noise maker vuvuzela.

i dont make this suggestion for buying one cheaper !
