paypal shipping and international?

Hey guys, I've just learned this week how to use paypal shipping (paypal.com/shipnow) to get tracking within the US on bubble mailers. awesome!

Now, whats the best way to use this for international, with tracking? i had it set up to cost just under $9, but it didn't seem to state it would include tracking. anyone have experience with this, and can offer assistance? I believe taking the to a post office in person would cost around $13+, so it would be nice to be able to get tracking for less than that
