Sending important documents abroad, what is the best way?

I was searching through the forum regarding information on sending application packets / documents via courier services. While there are a few threads on getting goods from abroad with online buying guides, I could not collect any useful information regarding sending documents (important ones). Hence creating a new thread which I hope will help me in taking a good decision. I have a few queries regarding this and would appreciate inputs from members having personal / relevant experience. As it is a first time activity for me, there are chances I may have missed out something important which must be kept in mind. Let me know if there are any. I need to send application packets (for my Son) to a few University’s abroad. My requirements are:- The service must be reliable Must reach in time Online tracking option for checking delivery status is preferred Must be reasonably priced Although I have discussed this with a few courier service teams, I do not have any experience with them regarding their performance. Some other queries I have in mind are- Which are the most preferred ones? Do they offer student discounts if there are more than one (say 5) University applications? I am told some of these offer discount coupons if the number of applications are more than one? Anything I must keep in mind regarding packing / packet size etc? Can I send original documents if required? Do the service / cost have anything to do with the country I am sending these documents to? I believe longer distance couriers will be proportionately expensive. Anything else to be taken care of or kept in mind? Would appreciate any inputs on this. Thanks in advance.
