SIGN UP FOR A NOTIFICATION LIST!

Click on a fully booked session: -and complete the order all the way to the checkout so that it shows as NOK 0. 
Then you are added to a waiting list. 
As soon as someone reschedules that session and it becomes available, you will receive a notification by email.

A helpful tip: Sign up for notification to the desired fully booked appointment, and then book another available time that also works for you. If the appointment you originally wanted becomes available, you can easily reschedule it at Min side.
