I'm not sure on what to do about RSVPS. After months of reading about guests not sending back their RSVP cards and having to call and text people for their response I want to make a wise and decision and save all the money I can. So I'm thinking of having two RSVP options. 1. Guests can RSVP via our wedding website or 2. Mail back RSVP card. Both of these options will be indicated on the RSVP card but do I have to include a stamp on the pre-addressed envelope? I'm guessing it would be okay not to since there is another option. Opinions please and thank you!
