I just calculated the price of buying a 5D III from B&H, shipping it to New Zealand and then paying duty/taxes on it. It comes in at NZ$800 (US$650) cheaper than buying locally, also putting it NZ$300 cheaper than a Nikon D800 in NZ. Nice.
I already have the 5D III, so it was just an exercise in currency and shipping, and I have no regrets in buying my camera when I did. My daughter was born 3 weeks ago, not today...
