We want to offer a special promotion for the TestDirector online course. 50% off for the 1st 20 students that are interested. The discount is not free though... We expect a feedback form and to tell us if you noticed any problems.
Also people that sign up will get future discounts on other courses.
The actual cost of the course will be $500, but we will offer it for $250 for the 1st 20 students or so who can give us detailed feedback.
Reply here or email firstname.lastname@example.org and in the subject note that you are interested in the promotion.
