Yes. There are typically new promotions as each new course is completed. Please check the promotions page (opens in own window) for the most recent promotions. Some of the promotions affect the price (but that also affects how much you make since you are paid on the final price for the course), but others just provide more value for their money. Many of these promotions are combined (20% off (first 100 people), plus the portal site, plus ALL the content, etc. (depending on which promotions are active at the time).
In addition, as an Affiliate Partner, you have a special advantage if someone orders through you–you can provide a coupon code for one EXTRA elective FREE ($495 value–equivalent to a 25% discount off the main course (without discounting)). Each main course includes a free elective, but they would have to pay for any additional electives unless they have your coupon.
