I have a question for brides who sent invitations to international guests. We are in the USA, but are inviting a few people who live in England. How did you stamp the RSVP card (or did you do something else)? I wasn't sure if the international postage I bought here would be the same needed to send the RSVP card back. I'm sure I can ask at the post office, but thought if someone here already knew it would make it easier. I wasn't sure if people actually sent RSVP cards internationally or used an online RSVP option instead. Thank you!
