I have a limited time course. Can I set it up so my clients can buy an extension for the time so they can stay in their same course and not lose their work? This is really important for them as they are learning math topics and those that need more time don't want to start over, just finish from where they are. Not all of my clients need this but some do and the extension is a revenue generator for me.
When a course expires for a student, they can repurchase the course again. This will essentially extend their access for the same amount of time and can continue with the same progress they have. If you don't want them to extend for the same time, you can set up an additional pricing option with a different expiration time.
Hope this helps!
