Ok, so you have hours of when I can cancel...clearly not because you have shift hours, since I'm talking to a machine. So why do you have specified hours?
Stamps.com billed me for 8 months before I noticed they were billing me. I only noticed it because I was doing my taxes. The billing size was just small enough to fly under my radar, but just big enough to hurt a bit. I feel that chose that pricing for that reason.
Anyhow, I saw they were in this story, so I felt I would expand upon their "dark patterns."
