I just cancelled a three month audible membership which I got for $0.99/month back in November. And today I saw on Amazon that I'm eligible for a free 3-month trial again. I know this has been a regular promotion but I haven't been eligible for quite a while (I've signed up for Audible trial multiple times with the same account). So I thought it might worth checking out.
