Click on Apply, then complete the purchase on the page after that. Yes, it now says "Apply" instead of "purchase" on these free offers, but nearly the same process: you must be in the US and have a credit card on file, make a "purchase" at zero cost, then the promo code is automatically applied to your account (no waiting for an email and dealing with a promo code). Sign-up for this offer expires June 2, 2013 or when the number of vouchers set aside by Amazon have been exhausted.
Grab a voucher today (before they 'sell out' or the offer expires) and you'll have a week to apply the voucher to your account and then 30 days to browse thru Audible and decide where to spend your $10. If you use it on some of the reasonably priced companion editions, you could get up to 5 audiobooks free from this deal.
Edited to add: I played with this a bit, to see what a "new" customer might be. It seems that not only those with a subscription, but anyone who has ever even logged into Audible with their Amazon account ID (or perhaps even if you just have an Amazon account) are considered "not new" customers. I know that an Amazon account that has no audiobooks and I don't think has ever logged into Audible was rejected as "not new", so suspect you'll need to create a new account at Audible (one with an email address not linked to an Amazon account) in order to use this voucher.
