1ds mk3 with a green dot on the box.

I just received my new camera and could not be more happier even though I have not use it as I am in office now.:)

One thing I noticed was that on the box at the bar code section there was an Green dot on it and a new sticker converted the old bar code.

The serial number is 636xxx and I ordered from Amazon last week.

Does anybody know what the green dot mean?

Thanks.
