May I jump in here ...
Where I live, there are two camera stores. The one that I mostly deal with are too small to have a demo at hand; as such, the cameras they sell are their demos too .. until they are sold.
As long that everything is in the box, all the bits and bobs indicate that the stuff is new then I am happy to take it regardless of shutter count.
But not only that, I'd much rather take a "tested" camera / lens than take one that's in wrapps ... who knows how well that will work :shrug: ... this I've leart the hard way. My, now sold, 24-70AF-S was spanking new and specially ordered for me. It had front focusing problem that took Nikon 6 weeks to fix. Had that been an unsealed, and "tested" copy, then I am sure I wouldn't have had to endure 6 weeks without it.
To the OP, since you were happy to walk out of the store with your "new" camera .. then accept it as it is .. it is a new camera.
What's 1800 clicks? On a good day, I'd take close to 1,000 shots with my trigger-happy fingers.
If you say it's a matter of principle .. yes it is, just go back and ask for a couple of SanDisk 4GB Extreme III cards and I am sure you'll feel a lot better; and have a happy relationship with a good store.
This is not to trivialise the horrible attitude that some may try to pull, if there was something being pulled on you; nor is this to trivialise the fact that it should have been sealed .. but hey, it wasn't long ago that men would kill for a "sealed hymen"!
We outgrew that, I think .. and look how much fun we're having now
foodposioson,
I noticed your last post "." ... I am guessing you've held-back on something; just let me say .. for a "kid"

you are a very mature individual for being able to hold back
