Hello all! I am in the process of ordering my invitations and I don't know if I should spend the extra money on RSVP cards. Do you think it's worth it? I'm just wondering if people will actually send them back or if I'd be wasting money getting them. I thought about having guests just email us to RSVP but I wasn't sure what would be easiest. What did or what are you guys doing for RSVPs ?
