As one of its daily deals, AmazonLocal offers an Audible.com $5 Credit for free. (If the offer doesn't appear, refresh the page.) That's among the best free Audible.com credit deals we've seen. (We've seen larger free credits, but only for new Audible members; this one is for everyone.) It's valid only for audio content, and can't be used for purchasing membership or gift cards. Deal ends August 26 or after 100,000 redemptions. The credit expires November 17.
