Our comiXology iOS does not have In-App Purchasing (IAO), but buying books from www.comixology.com and downloading in your iOS app is simple!
You can start by browsing the vast selection of titles on www.comixology.com. Once you're ready, click on the cart and head to checkout. If you don't already have your payment method on file, you can add that now. Once you're finished, you'll see a page saying the purchase was successful.
Jump back over to the app and tap the My Books tab. Now do a "swipe down" gesture to refresh your recent purchases. You'll see them populate and then you can start downloading and reading!
Additionally, you can use the Search tab to look for books and add them to your Wish List in the app. This will make it easier to grab those from the Wish List page on our site, so you put them in your cart the next time you checkout on our site. If you have any questions, feel free to shoot us an email. We'd be happy to help! firstname.lastname@example.org
