Promo Codes: Offer Discount for Books Added via a Registration Process SD425
As a person registering for a course, course activity, trip activity or an event, give me a discount on any of the books that I added to my shopping cart from the book page shown at the end of the registration process. When I'm viewing the recommended books page, during checkout it will show me the amount of discount I'll receive.
If I have a member promo code in the same cart, whichever promo code is greater will apply (the better deal). This book promo code will apply even if I register for the course at a different time.
