For new members only, Audible offers an Audible 3-Month Trial Membership for $4.95/mo. That's a savings of $30 and the lowest price we could find, although we saw a 2-month trial for free in January. This trial gives you a free audiobook download (of any price) for each month. (You can keep the audiobooks after your trial)

Be sure to cancel your membership before the trial ends to avoid a recurring $14.95 monthly charge.
