I started looking at Vistaprint the other day and for 70 invites, 70 RSVP's, and envelopes, it was going to be like $70. I went on today b/c I had a coupon, so they took my coupon on top of another special they were running...so I got all of that, plus envelope seals for $35!! We are not fancy, so these are perfect for us!
Here is the invite:

RSVP is the same exact thing but a white back ground and white lettering. The seal has a starfish on it with our names and wedding date on it. Super excited.
