Unfortunately, the United States Postal Service (USPS) is currently not providing shipments to Australia & New Zealand. According to their website:
“The U.S. Postal Service has TEMPORARILY suspended First Class Package International Service (as of September 3, 2021) and Priority Mail International (as of September 17, 2021) delivery to Australia due to carrier issues related to the COVID-19 pandemic.”
Because of this disruption, we are unable to offer an affordable free shipping method to customers in Australia & New Zealand that meet the minimum order threshold for free shipping. In lieu of this, we are reducing the cost of FedEx Expedited shipping services that meet the free shipping threshold until USPS is back online with Australia & New Zealand.
Thank you for your support and understanding, and we sincerely apologize about the inconvenience.
