About audio CDs and files:
Downloadable MP3s are MP3 files that will play on a computer or most smartphones and MP3 players, including iPhones and iPods. After purchase, you will be sent an email with links to the download files.
MP3 CDs are a single CD that will play on a computer, or a special MP3 CD player.
Conventional CDs are a two CD set that will play in any CD player. A 90 minute lecture will not fit on one conventional CD, so a two CD set is required for the entire lecture.
All prices include tax.
CD prices include USPS shipping and handling to your US mailing address.
If you have any questions, comments or problems with your order, please email us.
