Yes, Goodwin still does them. However, I very rarely see them on the job board. The scheduler usually emails me to ask me to do certain locations. There are some locations that seem to not be shopped.
I once got paid for doing a closed shop. Even if I had called before going, it wouldn't have done any good because the phone went to voicemail so I would have had to check it out anyways. It helped that I took a photo of the FedEx delivery tag that was on the door with a time of 10:17 am and I was there just after 5 pm.
