I spent almost 2 hours on the phone with Apple, and got it working. However, an “iTunes Download” does not mean the same thing to Apple as it does to the rest of the world. When you pay your $0.99, the file goes to your “Library,” which is just an Apple server. You can not download it to your computer or android device. I assumed it would be an mp3, so I was pretty disappointed. As near as I can tell by googling, I will not be able to export the file in any format.
The only reason I was messing with iTunes, was that the links to “Google Play Download,” “Amazon Download,” and “Audible” do not work.
I love Car Talk, and have rarely missed a broadcast since my local NPR station began carrying it in the late '80s. I load a couple of hundred episodes on my phone every so often to re-re-re-re-listen to! I wish we could get ALL the 1987 - 2007 episodes to listen back to.
