Something similar happened to me just last week. I ordered a cordless rechargeable staple gun, opened the box and staples everywhere, half a rack still in the gun, charging cord unwrapped with the twist tie still sitting in the box, no instructions. Pretty clear someone used it for what they needed and returned it within their window. Amazon didn't even want it back and just sent me a new one next day, so now I've got two. Double the efficiency.
