Last year American Express offered a free year of Calm subscription. Now that free year should be coming to an end since you had until December 31, 2020, to sign up. A regular premium subscription to Calm is $69.99 but Amex cardholders will get a renewal discount of $34.99. However, if you are a student, you can sign up for Amazon Prime Student and get 3 months free then renewal at $8.99 a year. You will need to sign up using a .edu email account and verify your status at a college or university.
