Same as this expired deal from February by Amazon Local. You will need an US Amazon.com account to obtain the coupon, a new Audible.com account to redeem the coupon, and a credit card to open an Audible.com account.
You probably will want to cancel the Gold Membership after you have "purchased" the second audiobook. During the online cancellation process, Audible.com will ask you for a reason. Select "membership too expensive for me" and Audible.com might offer you a $20 coupon to stay. Accept the coupon, spend it, and cancel your membership again. It worked for me last time.
