P&P unregistered airmail worldwide is $6US. Registered post is available at $17US but the service to countries is limited and compensation by the post office is a joke. Insured post is costly but is probably the safest delivery for valuable sendings. My policy is when it is posted by whatever method that is agreed upon, my responsibility ends the moment it leaves my hand as I cannot control the journey or the pitfalls the item takes on its way to you. Its progress can only be tracked at best should you choose a "track & trace" method of delivery. I only entertain refunds on the purchase price and not on the postage if I have wrongly represented an item offered for sale if it is returned within 7 days of receipt and definitely in the condition as sent by me. No refunds just because you have changed your mind. Posting to China, India, Thailand, Malaysia, Russia and other at risk countries with a bad track record for safe delivery need to pay for registered post.
For delivery within New Zealand there is the mandatory addition of GST without exception. You are deemed to accept all of the above when you bid. If any condition is unacceptable then please do not buy or bid on my items.
