Has anyone ordered internationally using USPS's (I Believe) EMS shipping service? I did a couple of days ago and was given a EMS express bill #.......so that I could track my order........I went onto the USPS site and input the information and what I got was "there is no available information at this time etc." is this common or are you suppose to be able to track package from the first day on? I guess it's possible some other company besides USPS is shipping my order........I did try UPS and the # was invalid......With USPS the # was valid but no information available........What's up? Anyone use this service before?
