We went a few days before our wedding to pick up our license, which we completed a pre-application for online. There was no line, so we went right up to a window. While the clerk reviewed our paperwork, we pitied the couples in the back of the office filling out paperwork together. After a few minutes, we paid our $77 (I guess the price went up? We paid in cash.) and left with license in hand. Easy!
Edit: Knocking a couple stars off due to an issue in receiving our certificates. I ordered two on October 2nd. My husband called two weeks later (allow for the 7-10 business days) and was told that it took 7-10 days to process, THEN they would mail it. A week later, still nothing in the mail. He called again and a helpful person told us she would put another copy in the mail the next day, which arrived two business days later. In short, if you don't have your certificate within a few days of ordering it, yours got lost.
