Course Sales Settings
If your portal is set up for sales you will be able to configure sales setting on individual courses.
Turn on For Sale and set a price to start selling the course.
Allow Discounts determines if any discount codes available for the portal will apply to this course.

Note: If the course is set to For Sale it will override any self-enrolment related settings. The course will need to be purchased by learners to enrol, unless manually enrolled by an administrator.
