Before we get started, make sure you have a Kindle or Kindle App-enabled device. Here's Amazon's official list. If you have an older Kindle that does not have Wi-Fi capabilities, you should use the standard download.

Now, you need to allow us to send you the books by adding our email into your Approved Personal Document E-mail List. This will not work if you don't complete this step. Really. It won't even kinda work.

1. Click here to go to your Kindle Personal Document Settings page. You will be asked to log in. After logging in, close that tab (or navigate back here) and click here again to take you to your Kindle Personal Document Settings page. (For non-US users, those links may not work and you'll have to find those pages manually in your account.)
2. Scroll down to Approved Personal Document E-mail List at the bottom and click Add a new approved e-mail address
3. Enter this address: bookhelper@storybundle.com
4. Now, find the section labeled Send-to-Kindle E-Mail Settings and locate the email address belonging to your device. It should end with a @Kindle.com and be something like your_name@kindle.com. Enter in your Kindle email on this page in the fields below.

After the books have been sent, you need to sync your device with the Kindle servers. For example, on an iPhone or an iPad, you pull down on the book list to sync.

You can check this Amazon page to see if the books have made it to your Amazon account. Amazon classifies any books not purchased through them as "Docs" instead of "Books", but that link will take you to the correct section.

Note: The Kindle servers have been slower than usual lately, so please give the books about 30 minutes to arrive. They will also show up a few books at a time due to processing on Amazon's side, and because the ebook files can be pretty large. Amazon has also been experiencing email bounce issues with using a free.kindle.com address (as opposed to just kindle.com addresses), so if you run into trouble, try using a kindle.com address.
