I was not aware of this program, so I decided to share it with everyone: if you work for the government, you can get a discount on Nikon products (I am not sure if this is specific to the military only or it is valid for any government agency). Here a post from a reader:
"No big secret, I just special ordered it through the exchange. I got my D200, D300, D3, and D90 all through them. The D200 and D3 I saved hundreds on each and got both when they were first announced and shipped to me in the Middle East each time. I have been pretty lucky with the discounts. When I got the D200 18-200 Kit I got 10% off of list and then and additional 10% off of that. The Nikon rep personally went to NY and yanked me one from another shipment when they found out I was in Iraq. The D3 I got 10% off on and got for 4500 when it came out as well. Nikon ships direct to you through the exchange program so its quick and when I got back from Iraq with my D200 and it was all beat to heck and outside of warranty by 2 weeks, they took it in and had it back to me a week later free of charge and looking brand new. Nikon has me as a customer for life."
Way to go Nikon!
