Thank you so much for this post, I was asked to review a book by an Author and for the life of me couldn't figure out how to get ibooks to allow me to redeem the code that she gave me. Thank you once again! Perfect, simple to follow instructions!
Step 1: Find The Redeem Button
1a.Open the iBooks app (on your iPad or iPhone or iPod Touch). If you don’t have the app installed on your device then click here to install the iBooks app - its a free app.
1b (optional). If you’re in “Library” mode browsing the ebooks you have already bought, touch the “Store” button and make sure you’re in the Apple store and not on your local device.
1c. Once you get to the iBooks Store page, touch the first tab button in the navigation tab bar (it is called “Featured”) on the bottom of the screen. Now scroll all the way down to the bottom, and voila! the “Redeem” button magically appears.
Step 2: Enter Your Promo Code
After touching the “Redeem” button, you’ll be taken to a new screen, similar to the one below:
After you enter your promo code, you should get a message saying that your item is downloading. iBooks automatically matches the product with your promo code, looks it up in the store and starts downloading it. Based on the strength of your internet connection, your book should be available in the Library in a few seconds.
