Hi, I got a digital download of them a few years ago, as my CD set had started failing. I love listening to the dramas.
I bought it directly from FotF, and they sent the audio file. I just saved it to my hard drive.

It' currently on sale for $70 US.

I still have the audio CD’s and they work fine, considering that they about thirty years old. I bought them as separate dramas for each book. They were purchased from a Christian book store which is no longer in business in our area.  I think that new sets of them are still available from the  Focus on the Family website and Amazon. However, I recommend supporting Christian bookstores if you have them in your area.

There's not really any Christian book stores, because most people now do shopping online. There is a Christian book store at Valley River Center in Eugene, which I'm sure they might have the Narnia radio drama set.

There are still a few of the bookstores around, but they aren’t so close to where I live. If it is a twenty five mile drive to go there then most people will shop online.  It’s kind of sad that many book stores are struggling to survive.

@narnian78 

If you still have your CDs, but want to listen to the stories on other things, can you copy them on? I've got one on my phone, for instance. 

There are still Christian book stores around, but they depend on people going in and buying in person. The two shops in my city have a lot of giftware to keep up their sales.

I don’t have anything else to make copies of recordings, but I don’t really want to listen to them on anything else since my old fashioned stereo has the best sound.  I don’t have the addiction to modern technology that so many people have and still use a landline phone. I do have a computer and an i-pad, which I use for this website.
