There is a local offer to sell a new D800 (zero shutter actuations, in box) for $3250, which is about the price locally with sales tax. Seller says he will give retail receipt with US model camera. Also, states that he pre-ordered and bought both D800 and D800e, and decided to go with the D800e, hence the sale of the D800. It would be a face-to-face deal for cash, so the camera can be carefully inspected. My question: Could I actually get full Nikon warranty support by having his receipt?
