So you are force to cancel the subscription before the renewal time and hope you don’t forget to cancel it.
I think the author actually means “force to cancel right before the renewal time (e.g. during the 12th month of a 2 year subscription)” because cancelling earlier means losing the rest of the subscription (according to the author). And if you forget to cancel during that short window you’ll be charged more money when it auto renews.
Perhaps wait and see what the rumored upcoming 40x0 Super cards will be like.
