We sent out our save the dates about a year in advance to around 200 people and asked them for a tentative RSVP. We sent a letter using neon paper from Staples, neon envelopes from Staples, customized stamps with our logo from Zazzle.com, a tentative RSVP postcard which we got free from Vistaprint, tropical confetti from Party City, and a save the date magnet. For the magnet, I had a graphic designer use a picture of us laying on the beach from a previous trip and add it into a different background which only cost about $30.
