So is this a download or a set of CD's??
This is a non-DRM free download. Audible is owned by Amazon but it will still require you to make an account. Sign up deals come and go. I've seen some where you get the first month free. Right now they have a get a free book deal.
The audiobooks work with iTunes on Mac and PC or if you don't use iTunes they have their own Audible download manager for PC. They also have an app for iOS, Windows and Android.
All this might be more info than what you were looking for but I hope it helps you and anyone else browsing the deal.
