First link says that he supposedly bought it for 5.

Yeah first link has some offers above 6 buds already. That Stormy Stormy Cannonball is apparently 7.1 buds.

Also the second and third link don't have any offers on the item. The second has a buyout @ the same price as the first though.

I'll close mine just to see what happens to yours. I feel some offers in the first trade exceed 6 buds though and I do feel this range is far to wide for an unusual.
