You’ll find details about your pre-orders in your Purchase History, although you aren’t billed until the book is released.

You can go to your purchase history and cancel a pre-order right up until the date the book is released. If your pre-order doesn’t arrive on the date you expect, it may be because the publisher has changed the release date or we weren’t able to process your payment.

You can check for an update on the Kobo website or the publisher’s website if your pre-order doesn’t arrive when you expect.

1. Go to Kobo.com.
2. Sign in to your Kobo account.
3. Click My Account at the top right of the page.
4. Click Purchase History.
5. Under Pre-Orders at the bottom of the page, you’ll see any books you’ve pre-ordered.
6. Click Cancel Pre-order beside the book purchase you'd like to cancel. 

Your pre-order will be cancelled and removed.
