Coupons are issued by instructors to promote their courses, gain traction and reach momentum. The instructor can choose to emit discounted (ex: $11.99 coupon) or 100% off coupon (you pay nothing). Each coupon becomes expired when emitted quota is over (1000 enrollments) OR expiration date has been reach (5 days).
For a coupon, number of activation are now capped to 1000 max. This means that it can be activated only a 1000 times, and then it expires; or reach its expiration date; whatever happens first.
We have no contact with instructors, and only instructors can emit coupons. You can try to directly contact the instructor finding his/her Twitter/Facebook, and ask him/her for a coupon, but at our level, we cannot help, sorry.
