Query: This camera was gray market.

This product was advertised as factory reconditioned with a 90 day warranty! The product was defective when received. Nikon informed me this camera was gray market with no warranty by Nikon in USA. This supplier should never be used by Amazon. The supplier also did not deliver as promised and did not return my phone calls! Problem was with this supplier, not the camera.
