I love the Paperless Post. http://www.paperlesspost.com/
Really cute invitations that are fun and classy. It isn't free, but I think the price is worth not having ads all over the invitation. I think they also have a pretty generous introductory offer that includes a bunch of free invites.
I agree with NWB. I love paperless post. They simply have the nicest, most elegant designs.
Another vote for paperlesspost.
