Ok ladies, help me out! I ordered really nice Passport Invitations from Zazzle, (super cheap, score!) and now my only question is, response cards? I set up a website on The Knot and wanted to know if it was cheesy to set up an Online RSVP? I think it makes sense, and saves some money on postage, etc. BUT, along with the passport invites, I wanted to include the website info, etc. How should I go about doing this? AHHH! Help!
