Does the content of some of your courses overlap?
Right now, the only course materials that overlap are the Ultimate Guide to Grant Writing and Grant Writing Made Easy.
Everything included in the Ultimate Guide to Grant Writing is also included in Grant Writing Made Easy, so if you're a member of GWME, you do not also need to purchase UGGW. If you'd like to upgrade from UGGW to GWME, use the special discount link on the course site. You can log in to the course site here.
All other courses and products are different and independent from one another.
