When you order an eBook, the website will automatically send you an e-mail with the order confirmation. You'll receive a unique redeem code with every ordered title.
You'll need these codes to redeem your comic on the website of the distributor or in your eComic app that can be downloaded on your IOS or Android device.
Surf to www.digitalcomicsreader.com for reading online and links to the Apps.
note: at the time of writing (June 2013) the Android app seems to have downloading problems in newer Android 4++ versions.
A work-around is to download the "Comicsplus" app , which is also made by Iverse, this will automatically add your redeemed issues.
