Yes, I think you should take the course. Sounds like you got a break. I doubt police will come to your house, cuff you and drag you in for ignoring it. BUT skipping it makes any future encounter with a police officer potentially much worse for you. You're now in their computer. I also recommend that you confirm that the cheapie on-line school you found is an approved school to the court. It may or may not be. I imagine they have a list of approved schools. Put it this way, if it's not approved, it could be as if you did not take any course at all, and then you'd not only have to pay again, but take yet a another course to satisfy the sentence. I say find an approved school, pay the extra money if necessary, and take the course. Then you can move on without any risk.
