I used pirateship.com, which I learned about on this forum (Best shipping options for BST? - #3 by vegabomb), to ship the blanks via UPS’s Worldwide Expedited service (the cheapest at the time). I recall the original shipping cost was close to the amount that CWP quoted you to ship one blank, but I failed to take a screenshot. I paid just under $81 to ship them to Australia from Illinois.
I can’t explain why the delivery was so fast. The estimated delivery date was May 23rd.
