One year of Audible 33% off – 12 credits for $99 – targeted email? – YMMV?

I got this email on one of my Audible accounts, but not all of them. It seems as though it only works for non-active accounts.
12 credits all at once for $99. It will renew at the full price of $150 in one year. Fine print says that this offer is not available to existing Audible members, or customers who have been paid Audible members in the past 30 days, so YMMV.
