Happy ending. In fact, very happy ending.
It is a 7D. The box was previously opened; however, that was only to separate the kit lens (EF-S 18-135 IS). Everything else was in its original wrapping, etc ... There was zero shutter click. I took 2 test shots with my Tamron 17-50/2.8 and my Canon Speedlite 430 EX. Those were shots #1 and #2 registered by the camera.
The original receipt was included. It was from a Canon Authorized dealer. The kit was purchased 2 weeks ago!
And I paid only $1280.00 for this! 
Thank you, everyone, for your responses and advices. Now I have to go play with my new camera
