I've waited a day to make sure it worked, but this CNet article is onto a great deal. I've checked my account details, and have 1 credit, and have been charged US$1.95. I had a membership last year (and cancelled it), so this is one of those rare, not just for 'new members only' Audible deals.
Note that the price will revert to $14.95/mth after the 3 month period (thanks SmiTTy), and you can cancel at any time.
CNet also says; Surprisingly, this deal is good not just for new customers, but for previous members as well. (If you're a current member, I don't see why you couldn't cancel, then sign up again via this offer. That's gaming the system a bit, but that's how you earn your cheapskate bona fides, right?)
pricing only valid for 3 months by the sounds of it :
At the end of the 3-month promotional period, your Audible.com subscription will be renewed at the then current full price (currently $14.95 per month) with your Audible account credit card.
Good deal though . This would equate to 3 audio books for $6 vs some of the other deals where you get 2x free audio books at initial sign up.
