Sorry to hear of your debacle, but at least I can say I did try to warn you. I belive I also told you that any Nikon Authorized Service Center would do the repairs for you, just NOT the Nikon USA Warranty Centers in Melville or El Segundo. Nikon USA is an independant corporation from Nikon Japan and pays a LOT of money to have exclusive US Distribution rights for Nikon products. They are also fully responsiblr for warranty repairs on all those products and its the salesprofits that pay for all those repairs when needed. When an UNAUTHORIZED importer buys a container full of Nikon gear in Singapore or Manila and ships them here to sell at a discount they are not responsible for making warranty repairs so they can sell them cheap. Why should Nikon USA have to pay the cost of repairs to those items? They shouldn't, and they don't.
When you buy a Nikon product you get a physical Nikon USA warranty slip inside the box with amatching serial number. If you don't get that slip you bought grey market and will be out of luck for any repair at any time. Warranty repairs require TWO items, that slip AND an original receipt with your nameon it and from an authorized retailer.
As a camera dealer I can assure you I never take an item inon trade without that proof of USA purchase entirely to assure whoever buys that item from me will never have an issue with future service.
My 5th D600 is on its way back from Nikon with a new shutter as I writethis. At no time did any of them show any more dust than any other DSLR I rent out or own personally, regardless of brand, but the work was free and Iincludes a free CLA to boot so they all went in one at a time. Kudos to Nikon for doing so, and replacing some with D610s for those that cry the loudest.
The key when you buy ANYTHING online is, prepare to be ripped off 50% of the time and you will never be disappointed if you do. Always buy from reputable sellers. And ANYTIME something is priced significantly lower than every where else, there is a good reason for it, and that reason is never going to be good.
So lick your wounds and enjoy your gear, get it cleaned and serviced if needed, or sell it all and downgrade to Canon if you want, its all your choice anyway.

Sorry you got caught in the web of international distributorship. There are several item groups that will only honor the specific warranty of the company through which you purchased the sales. In your case, your Nikon can be CLA'd or repaired by any number of Nikon Authorized Repair Stations throughout the country. These are not fly-by-night companies who just happen to have a "Nikon Technician" on staff; they are established companies that have equalled or exceeded Nikon's rigid criteria. Like I said, they will CLA your camera, BUT YOU WILL PAY FOR IT. If you had a Nikon USA warranty, NikonUSA would pay the bill; you don't, you will! You will receive the same high quality service you would get from ANY Nikon repair station. New parts will be Nikon OEM, and you might even get a repair site warranty (30-90 days) on parts and labor. In Sacramento, CA, that warranty station is shown below. I have done business with them for many years and have NEVER been disappointed.

Thank God there is no actual ink being spent here, just virtual ink!
The OP sure has got his $27.00 worth on this subject!
I am surprised nobody here seems to consider the import/export rules and regs and the penalties that go along with bypassing any of this!
After many decades of regulation I am sure "Big Name" product companies know where their interests are and they do not want to draw the attention of the Feds in their business!
A lone noisemaker here and there such as the OP is just a nuisance but is still Illegal activity and his camera could just be confiscated by anybody in the business!!!
Btw, nobody "Exiled" him although that would be a good idea!
8-)

I sure got $27 worth of responses. Hey I told Jerry, MT, and Dave that I would report back to them, I value their opinions as I do all of you UHHers. Ok so I got a little dramatic. But I never thought that this would create the hailstorm of responses that it did WOW! And this is why I love all you fellow readers who so dramatically responded. Isn't this a great forum? By the way what's an OP? Thanks to all of you who replied so passionately, now let's have a virtual toast with a nice glass of virtual wine, calm down and make some pictures. Thanks again to all.
