To help save money on postage I was thinking about having a online RSVP or a wedding website. Will I still have to send out RSVP cards to the people that I know would go online to RSVP? And if I still need to send RSVP would I have to include a stamp for that and still have the option to RSVP online? How would we word if it we did RSVP online? *We are not doing save the dates*
