Do sessions expire? After I buy them, how quickly must I schedule them?

You can schedule sessions for up to 6 months past the purchase date. They can be scheduled for a date past their expiration date. For instance, if you purchase 10 sessions on July 2, 2020, you must schedule all 10 sessions before January 2, 2021. You can take any of those sessions after January 2, 2020, as long as they were scheduled before January 2, 2020.
