If Chins Could Kill Signed.

[Count von Count]

I'm a big fan Bruce Campbell so I was happy when I recently found the Bruce Campbell book "If Chins Could Kill" Signed,at a book store. I'm no expert in priceing signed books.
So I'm ask on the Forum, What do you think the price should be?
The book is a 6th edition, if that helps anybody.
I know the price the store wants to sell it for, I just want to see if anyone here comes up with the same price.
Thanks For Helping Me Out.

Ok so I have been looking on all different Book Sites and No-one Has it.
I think that might make it rare. I would still like some help here though.
