A very sad account of your service experience. My reply will not likely be of any help but the purpose is to suggest how important dealer support can be. I bought my D800 at "London Drugs" whose headquarters are in your neck of the woods. I have always dealt with LD for photo gear and they will match the lowest price I can find elsewhere as well. Anyway, I also had the focus problem and upon discovering the cost of insurance and shipping I simply took the unit back to LD although about 2 months after their in-store warranty had expired. After all, they are always bragging how they stand behind everything they sell. The sales rep instantly took the unit from me and said "You paid a lot for this camera. We'll insure and ship it back to Nikon at our cost." Which they did and not a cent of cost to me. He also said if I was not satisfied with the repair they would give me a new camera off-the-shelf although it never came to that. I'm in Calgary and Nikon service is rendered out of Toronto. I had my D800 back in less than 2 weeks working perfectly ever since.
