Amazon is offering 4 free audiobooks when using an Alexa device to start an audible trial. It states for new subscribers only, so YMMV.
How to get 4 free audiobooks:
1. On any Echo device, say "Alexa, start my Audible trial" to start and follow the prompts to sign up.
2. Four credits which can be exchanged for any audiobooks will be applied to the account registered to your device. Ask Alexa for any book to redeem them, or browse audiobooks to find a title.
3. Listen on your Echo and download the Audible app for iOS or Android to take your story on the go. Keep your place even when you switch devices. After one month, your Audible membership will renew at $14.95 for 1 audiobook credit/month. Cancel anytime.
Offer valid from 2/1/2019 at 12:00 a.m. PT until 2/8/2019 at 4:00 p.m. PT or while supplies last. Offer available only to new Audible customers who sign up for an Audible trial on an Alexa-enabled device through voice sign-up. You will receive a 1-month Audible free trial that includes 2 credits as well as an additional 2 bonus credits (for a total of 4 credits). At the end of the free trial, your membership will continue until cancelled at the then current full price (currently $14.95 per month) with your designated credit card or another available card on file. Cancel anytime by visiting the Account Details page. After you sign-up for your trial membership and your payment information is verified, your Amazon.com account will receive 2 additional bonus credits to be used on any audiobooks on Audible.com or Amazon.com. These bonus Credits may take up to 48 hours to appear in your account. You must use the 2 bonus credits within 365 days of them being added to your account. The credits will be applied to the Amazon account that you used to sign up for the Audible membership. Offer is limited to one per customer and account, is non-transferable and may not be resold. Audible and Amazon reserve the right to modify or cancel the offer at any time. If you violate any of these terms, this offer will be invalid.
