For my save the dates I used a photo/digital scrapbooking software and made 4x6 pics with our picture, and save the date info. They looked really nice and then I slapped labels on the back and mailed them as post cards. They were really cheap since it was like .15 a print and then a postcard stamp. If you want to know the name of the software just send me a msg. I don't want to break any rules and promote a particular company. Just passing a long an idea.
