Words cannot express how happy I have been with Minted.com on both a business level and a personal level. For business, we use them repeatedly for customers that need day-of printed materials, invitations, save the dates, etc. The feature that everyone loves is the quick turnaround time, especially when those escort card deadlines come along.
Also, we use them year after year for our holiday cards, and with their free recipient addressing, it makes sending out holiday cards a breeze. They look professional and creative all at the same time. In fact, most of the companies on our list will be receiving their cards on Monday!
Personally, I use them for nearly every invite I ever send out, and definitely every year for our holiday card. This year I was able to order our cards early enough that they actually already arrived and are ready to ship out today to our friends and family across the country. Having them pre-addressed for me makes all the difference, as that used to take me 2-3 days to complete!
