Is there a way to set an appointment from home instead of going in and waste people's time at this weather?

At present there is no option to take appointment from home. You have to go there take appointment and come back 5 minutes before appointment time. This is far better than waiting in the snow for couple of hours. May be in the near future, you will be able to take appointment from home

Go on there website and see what you need. You can make your decision at that point in time.
