Limited quantity free voucher for $10 to Spend on Audiobooks from Audible.com
Here is a Amazon Atlanta local link, not sure if the deal applies to all cities.
This is getting interesting, I was able to apply the code to existing audible.com accounts and was able to stack voucher codes as well. Steps below.
1. Get your voucher here http://local.amazon.com/atlanta/B00A82DN54
2. Once you get your voucher, wait for it to post to your amazon local account. Click your vouchers and for this deal you purchased click view code.
3. Click the link in step 2 in the page, it should say "Click here to begin the redemption process at Audible.com."
4. Apply the voucher to your account
5. If you have another voucher code you can go back to previous page (may be 2 pages back) from step 4 above and enter another code, this way the $ would stack to the same audible account.
This worked for me, so let me know if it did for you.
