What are the ways to send small amount of money from United States to Singapore, besides wire transfer?

Well, if you would like to consider regular post via airmail here's what you do: make sure that you put the money (paper bills $) inside a carbon paper so that who ever will check to see if there's money inside won't see anything except for the paper which you used for your letter. We do this all the time :-)|||Consider PayPal, easy cheaper %26amp; less risky than mail.
