I called the store after finding out that my insurance no longer covered my old optometrist. They were able to see me later the same day. There was no one in the store when I arrived around 5:20, but another person came in right after me and then someone came in early for a later appointment. I got to go first as soon as I finished my paperwork. First you see a doctor's assistant and then you see the doctor. They had me in and out quite quickly without seeming rushed, although the person who came early for his appointment was still waiting in the front as I was paying.
They have everything they need on site and offered to send me home that day with contacts. I wanted a specific brand they didn't have, so they are ordering them for me and matching the price of the online contact stores. They said they would call me in a few days when they came in.
Overall, this was one of the most painless experiences I've ever had trying to renew my prescription and refill my contacts. Excellent set up!
