Once you sign up, you’ll receive an Audible credit loaded automatically to your account each month. You’ll receive a total of 3 audiobooks for free over this 3-month trial.
Be sure to cancel your subscription if you do not want to continue after the three months is up. Otherwise, the charge is $14.95 per month. The audiobooks are yours to keep and you can always buy and listen to select audiobooks on sale (or free) even without a membership.
