This is going to sound nuts, but I'm going to get my invitations from Vistaprint.com. I'm gonna be able to create my own invitations and get 200 of the invitations and envelopes (no response cards, but I think I'll just use a business card template for those) for $72. And they're seriously good quality! (I ordered a few samples to see, and was very impressed!) They also have some of their own designs, and if it were more in kepping with my very-hard-to-match theme I would absolutely go with one of their designs.
