What template websites have you used to create and print your own save the dates, invites, and RSVP cards?

I have been looking at the artificial and real flowers and both are fairly expensive for my budget. I was wondering if anyone has done anything else besides flowers for their centerpieces?! Need ideas!!

Does anyone know where I can get inexpensive postage stamps to send out my save the dates, invitations, and thank you cards?! Also, does anyone know where I can find cheap colored paper (cranberry/burgundy) for the invitations and envelopes??
