Forgetfulness turns into money savings, and as a bonus I get to review whether I am getting much out of it. Especially for tv like disney/netflix/apple tv, I often run though everything interesting and don't have much else to watch with them.
Also psychologically there's resistance to a boring to do that involves loss. I will put off "go to netflix and figure out how to cancel." So do that work when you are excited to see the new show.
