Eh, that scorching belgian sale is tricky. That knife sold for an insane amount on the SCM and I think this dude sold it on the scm too

That exact same knife has a seller at 85 but is probably lower in reality. Total sale there will be a little below low end

There's also this sale (which belongs to your 240 seller) which would put this insanely low.

Due to his reselling value its obvious that the seller just severely overvalued the stare thingy

This is probably slightly too high but close enough
