Semesters and Courses can be discounted in price each day as they progress.

Using this feature encourages customers to make a purchase even if they have missed the start -- so they don't feel like they're overpaying.

To update these settings:

Click Settings > under Host Account, click General Setup > about halfway down, click Enable / Disable next to 'Enable prices to be pro-rated for courses' or 'semesters' > Save your changes at the bottom.
