Ugh. I CRINGE when I say that. Unfortunately, when I mention it, they usually say well, the lens was sold as open box and we don't have another one to put on...and I'll tell my manager. I'm sure I'm known at my local Best Buys as that crazy Nikon guy that always taking about the cameras not having lenses.
(Cameras, like TVs are probably sold as display models or open box specials.)
