So, I have no plans of getting a calligrapher and did not have addresses included when I ordered my invites. Yup we ordered and got them already!

My plan was to use a mailing program I use at work that I could print them on small mailing labels. Free and pretty simple.
However, in the past week I was offered a new position with another company and am leaving my current company. So now I cannot print the labels.
My wedding is not until October so I wasn't planning on printing the labels for a few months.
Does anyone know of any websites/online companies that provide this? Just curious.
Thanks!
