Can we create some standards for using "NIB" and "BNIB"?

If a gun is out of the retail store how can it be NIB or BNIB? Unless the seller is FFL.

And how would one EVER verify that 100%? One should treat this like vehicles where once you drive it off the lot it's no longer new and is now used.

I think we should revisit its use just for the simple fact we don't know if the seller has sent down 1,000 rounds through the gun or 1 or none.

Food for thought
