ChristianAudio.com is currently selling downloadable audio files of the 2008 C.S. Lewis Summer Institute.
Every lecture is available separately, so there is flexibility concerning which sermons or lectures you choose to buy.
The individual CDs are $7, while the entire series (the whole 2008 conference) is available for about $100.
We are planning to make audio from our other events available in the future. More information to come!
