I have a McFarlane Movie Maniac Alien Queen I've had since teenage years that I've been thinking of parting ways with for a long time, I've never gotten around to it because I have no experience with selling online to be honest.
It's never been opened and the box is like new, just some vague marks that'd you expect from it being caked in dust in some forgotten corner, but after giving it a wiping with a swifter duster sheet it's pretty damn good overall I think.
And now that I'm looking it up on ebay the average looks like anywhere between $180 and $230 CAD. A couple over $300 but I think that might be pushing it.
