contact either ups or your postal agency, they usually have a start fee for heavy items, if its not a heavy item it then depends on how far it's being shipped and how quick you want it to get there and a few other things.
other wise you just have to wait until the person tells you where they live and contact the postal agency with the to and from zip codes.
hope this helps.
