I'm struggling to figure this one out.

I looked, the seller has positive feedback for the sale, so it doesn't appear to be fake bids.

Its not even sealed! I think that is a little high for a MISB, but for an opened MIB piece? Hell I'm pretty sure I could put my MP Grimlock back in the box and say I only transformed him once, and he has been sitting out on my shelf since I got him for the most part!
