Audible currently has a great deal that gives you $50 off any Echo device and $50 off an annual membership. I’ve seen each of the $50 discounts available individually in the past, but this is the first time I’ve seen them available simultaneously, making this a killer deal. A 12-month membership normally costs $149.50 and includes 12 audiobook credits. With this deal, you’ll pay $99.50 for those same credits, which will all be available immediately, and a $50 credit good towards the purchase of any Echo device will automatically be added to your Amazon account. Each audiobook credit is used to purchase one audiobook, for a total of 12 books, that you own forever, even if you don’t renew your membership. Some larger titles might cost 2 credits. This offer ends March 25th and you must use your $50 Echo discount within 14 days of signing up. Past Audible customers can also take advantage of this offer.
