We strive to increase the collections' sound quality and any additional episodes. If the collection is updated with a better sound quality or additional episodes, an email notification is sent to previous listeners that new collection is available at a discount price.
Upgraded collections are available at up to 40% off for previous purchasers.  You can view your complete order history which shows you all the possible upgrades and discounts for your account by:
1. Login to My Account 2. Click tab: My Purchased Disks
Once you are logged in, you can also review a list of all your previous orders. If a collection has been updated since you ordered, you can buy the new updated collection at a 40% discount through your web portal login.
