Get your first 30 days of the AudibleListener Gold membership plan free, which includes one credit. In almost all cases, one credit equals one audiobook. After your 30 day trial, your membership will automatically renew each month for just $14.95, billed to the credit card you used when you registered with Audible. With your membership, you will receive one credit per month plus members-only discounts on all audio purchases. If you cancel your membership before your free trial period is up, you will not be charged.
