PayPal is fine for international orders of $100 or less, I will email a cheap airmail postage quote.
International orders over $100, who do not want to pay for Express Mail, should not pay by regular PayPal, unless they are willing to assume the small risk of loss themselves.
Most of my customers pay by PayPal, a wonderful tool saving the buyer the cost of a stamp, a means of immediate payment, as well as guaranteed delivery.
PayPal accepts tracking as proof of delivery. Tracking, free on many domestic parcels, is only available internationally thru Express Mail. PayPal WILL NOT accept Registered Mail with signature confirmation as proof of delivery. When international proof of delivery is required shipping is much MUCH more expensive. A recent 7.5 ounce order to Norway was $13.50 by uninsured airmail, or $59.50 by Express mail. On this order I asked the buyer for $10 for uninsured airmail, or $40 by Express mail.
I want every buyer to have protection against loss, but Express mail is so expensive, and losses of uninsured airmail shipments are RARE, so I want my international customers to have a choice.
Please note: Australia mail delivery has been extremely slow since COVID, and though the packages normally eventually arrive, I can no longer guarantee delivery in a timely manner, or at all by plain airmail.
Customers choosing non insured (regular airmail) shipping on orders of $100 or more must assume the risk of loss.
