Nine Free Audiobooks at B&N store

Barnes & Noble opened their Audiobook store this weekend. As a promo they are offering nine titles as free MP3 downloads. I noticed that each title is listed at a penny a piece, but when I clicked through, the total was zero dollars at the checkout stage.  You do still have to enter a valid credit card to get your free audiobook, though.

These nine title will be available until 3 a.m. on May 16th.
