My last haircut was $15. They don't take appointments, but if you use their online check in it will tell you how busy they are and you can put your name in ahead of walk-ins.
I don't know the price of a woman's haircut, but if you download the Great Clips app, you can select a location and put your name on the waiting list. It will tell you how much time till your appointment.
