For Australia and England add $50 to your pledge. The mailbox will be sent via US Postal Service Priority Mail International. Expected delivery is 6-10 business days to major markets.
For other countries, click the "Contact me" button (below my photo) and let me know the country and I'll reply with the amount to add for shipping.
A big thank you to Kelly in Australia who informed me that the good old USPS has better shipping rates than UPS, DHL, and FedEx (all wanted $250 plus!).
I would update the pledge boxes for this, but after receiving one pledge they are 'locked' by Kickstarter.
