The thing about pre-orders is so long as the site doesn't charge you until the item ships, companies can say whatever they want. Why we mention all of this of course is Negri Electronics are offering to take your $649.50 for an unlocked Nokia Lumia 900 in white. A device that hasn't even been announced officially yet (though we think the it probably exists). We checked out the site via Reseller Ratings and they have a respectable 7.5 out of 10--so they're not a complete scam if that makes you feel any better.
As mentioned above, they won't charge your card until it ships but either they have some early info or they're aiming for some site hits for publicity. We're about 50/50 split on that one, so we're not exactly ready to endorse this as legit, but hey it's your money.
