Hi guys, I'm Aditya.

I'm planning to apply for a few universities in US for fall 2015. I wish to know the following:

1.) What's the cheap and best courier service that can be used to send the transcripts and other supporting materials to the universities ?
2.) Approximately how long might it take for the courier to be delivered ?
3.) Will I save money if I ship the documents to all the universities at once ?

Please reply ASAP

thank you
