I fix this by using a one-time card number for any subscription or recurring purchase. Citi and Capital One offer them for free (the latter has a much better UI), or a lot of people use Privacy.com. Even a Visa/MC gift card works well if you happen to get one for a rebate or something. It would be great if merchants all abided by #2 and gave notice of impending charges, but ultimately I prefer to shut off the taps on my timeline rather than theirs.
