Track Day Junkie
Good brand with limmited use, ie Suter, STM etc. Must be complete and minimal wear. Paypal required with USPS PMI to Australia.
It is short for Priority Mail International. 6-10 day airmail with international tracking and optional insurance but significantly cheaper than the 3-5 day version (EMI - Express Mail International)
PMI does support online tracking internationally. I have used it on a number of occasions. See more info at this link: http://www.usps.com/international/prioritymailinternational.htm
Hey, any one actually have a slipper available rather than postage queries...
