Today we decided to discontinue Air Mail (untracked) shipping to Australia. Why? The service has been taking longer in recent months, and I just learned that if a package isn't delivered within the stated 21 business day window, the customer can go to Paypal and get their money back - even though the shipment can be delayed in Customs, and the package can't be returned, it will be delivered to the customer even though they got their money back.
So, in the interest of fairness all around, I will only be offering tracked shipping to Australia, which is more $ than Air Mail, but then both you, dear customer, and I, have clarity on the package status. Books are ANGELS but they don't have wings!
