The sign-up and advertising is very misleading. They advertise $25 and that the certificate will be emailed to you -- but the email is an additional $30. Other online courses are much more reputable. SafeDriver does NOT show you BEFORE you pay the $25 how much it will cost to have it e-mailed. Others will. Do yourself a favor, save money, and take another course.
Also -- don't believe the ShopperApproved reviews they have - those are bought and paid for.
