So this just occured to me today, and I haven't seen it addressed anywhere:
I know it takes extra postage to send mail from the US to other countries; but what do I do about postage for the RSVP card? Can I put US stamps on it in the same amount it would take for me to mail an envelope that size/weight from here to there, or do I need some other sort of fancy postage?
