Popular Web sites that sell e-books like Amazon and Barnes & Noble allow you to preorder titles with your credit card. Google Play Books now offers the ability to do the same, from the Web or your Android device.
To allow preordering of titles, you'll need to make sure you have a payment option available in Google Play, like Google Wallet or carrier billing.
Step 1: Open Google Play Books in your Web browser or on your Android device. When using an Android device, just open the Google Play Store and tap on Books.
Step 2: Search for the title you want to preorder. If you're not quite sure of the title, Google has been nice enough to include a New and Coming Soon tile on the front page of the Books section in the Play Store.
Step 3: Press the preorder button and choose which account you'd like to pay from, then click Accept & preorder.
Note: Your credit card will not be charged until the book is available for reading.
All e-books you preorder will be shown on the My Orders page and you'll also receive an e-mail receipt for your purchases.
