morning cow invitations

has anyone used morning cow for their invitations? i found them online, you buy the software and cardstock and design and print your own. of course we found an example of a thank you that we love, but i'm not sure if its worth the trouble of printing all that stuff ourselves.

i included a link to the thank you as when i tried to upload it, it wouldnt show up
