When you create a discount coupon, you may want to track which coupon students used to purchase your course.
Here's how you can easily do that!
In your Students page you'll see a column which lists the affiliate code that was used by each student (if it exists) and the coupon code (if a coupon was used)
In the detail page for any Student, you'll be able to see the coupon that was used to purchase each course (if one was used):
You can also perform an CSV export of student data while filtering on either the "Affiliate" or the "Course" filter (or both). The report will include a column showing whether there was a coupon used for the purchase.
