Attn Australian Customers: We ship our cassettes in padded mailers. Australia Post will calculate the postage for one (1) cassette as a Package - $9.30. To save postage costs, we can post cassettes in a business envelope which will usually cost $2.70 for a single cassette. Please email sphereofapparitionrecs@gmail.com to make these arrangements OR place a note during the checkout process and we will refund the difference. Note: No responsibility will be taken by SOAR for cracked cases/cassettes if posted in this manner. Secondly, due to the rigid structure of the platform we use when trying to calculate postal costs, any excessive postal costs incurred by you (particularly when buying 3 or more cassettes) will be addressed and refunded accordingly. Thank you for your understanding.
