Dear International Customers (yes, you too, Canada):
We are flattered you're down to rep QS in whatever distant corner of the world you might reside in. However, international shipping through the U.S. Postal Service is expensive, especially with tracking, which is the only way we will ship. If we use cheap shipping methods without tracking, we are essentially throwing your package in a hole and hoping it ends up on the opposite side of the earth, with no ability to see where it is, or if it even arrived. Sorry, our shipping policy outside of the U.S. is not negotiable, both to protect your items/money and ourselves.
On the plus side, the only method the USPS provides of tracking international packages is Express Mail, which means you will get your items quickly, customs delays withstanding.
