I'm so excited that my invitations just got here! I bought a design off of etsy and then had them printed by Vista print. Vistaprint was so affordable and I upgraded to the linen paper. Design fee on etsy plus my printing on Vistaprint came in right under $150 (for 100 invites).
The one issue I had with Vistaprint is that I ordered flat invitations and then RSVP cards and they are in the same size. I called customer service and she credited me the cost of the invites so I could go back and order a bigger size. So I was very pleased with how they handeled it especially b/c the order was correct. The website doesn't show the size of the items very well so it was really my fault for not verifying the size. I just assumed RSVP cards would be smaller than the invites.
For my FI and I we didn't want to spend a lot of money on the invitations. We also did not want very formal ones. Okay sorry this turned into a long post. Here is my invite:
