I like that it's easy for students who are not familiar using computers (and even those unfamiliar) can use this product without having any problems at all! The customer service support also has been very helpful as well from time through out my experience of working within their office in California!! Nothing really specific about course merchant itself but rather just how much they have helped me throughout these past 2 years while we've worked together; so many times when you need help there always seems too be someone else ahead making things more difficult than necessary - however if one person isn't around then another will step up & do what needs doing until he gets back into work mode again :).
