Postage from Italy to US

Question

I am about to mail out my wedding invitations and inside is the response card with an envelope. Normally, the response card will already have postage included. These will be coming from Italy back to me in the US. How much postage should I include on the response envelope? Can Italy use american postage?

Answer 1

Go to the post office and ask them. They will know and be able to put the correct stamp on the envelopes for you. (And no, Italy will not use American postage)

Answer 2

I sent a postcard from The Vatican on vacation. If you go to a post office (or sometimes souvenir shop,) you can just say, stamp to U.S. and they give you what you need. That's what I did.
