Received an in app notification from Audible for a free trial if I returned. 30 day trial, starting with 2 free audible credits (only 1 if you don't have a Prime membership FYI) and 2 free audible originals. Basically the same deal as they currently offer for new customers, but don't need to go through any hassle of making alternate accounts or anything.
From what I can tell this must be done in app - there was a large banner when I opened it. I'm assuming this was targeted, but perhaps anyone who has had an account in the past and cancelled is eligible.
