There are some benefits to doing preorders on Kindle, but the main drawback is you can’t get reviews posted on a preorder book until after it’s live.
Or can you?
Actually there’s a way around this: Set up the book on Createspace also. Publish it to Amazon.
But then, upload a new interior file and don’t approve it. The print book should show up as not available but you should still be able to post reviews on the print version of the book (and since the Kindle version and the print version share reviews, they’ll show up on the preorder Kindle book.
So clever. Hat tip to Megan Crewe.
I’ll make a video about this process later and add it here.
