do you go to uci?
does your school have a preprofessional office that stores letters and send them to multiple schools as you request?
if you do, then you only need one copy and store it on file at the preprofessional office's database. They will copy them and send them to as many schools as you request.
If you are asking letters from professors, boss, etc and you send directly to aadsas, it might be a good idea to request 2 copies, one to keep for yourself, one to send it to aadsas, because sometimes aadsas might lose it, or it can get lost in the mail, and it would be too much trouble and too much time to ask the prof or boss to make another copy and re-send it, it might take longer than you want.
hope that helps
