The meal box kit things seem to be the worst for that shit here. They don't let you cancel your first box, even if you want to do so 10 minutes after you sign up, and you have to cancel a week or sometimes 2 before they prepare (not even send) your box. Then when you do cancel, they have 3 or 4 rounds of questioning where they'll swap the position of the "yes I'm sure" button, as well as changing the colours to try and trick you into clicking "no I want to stay".

I also signed up for an online news site once. It was a $1 trial for a month or something like that. Annoying, but I wanted to read an article no other news site had. Then the only way to cancel is to call them. Being ADHD as fuck, it was on my to-do list, but I forgot I even had a to-do list and I forgot. Then the subscription renewed at like 30 bucks a month. They weren't even transparent about the renewal price, I didn't see it anywhere when I was signing up, so I assumed it'd be around the same price as Spotify or something.
