auskiwi, thanks for the suggestion to call Crown. I just got the quote:
Quote: US$4350.00 per 20ft container ( Door **** Arizona to Port of Auckland, New Zealand )
Yahoo! Half the price of the previous three quotes. However it is only to the Port of Auckland.
Quote does not include destination’s customs clearance, duties and taxes, and is subject to destination charges payable in local currency and any destination regulations for this commodity/shipment.
Any advice on what the charges might be for things that aren't included??
