Pre-order button - wishful thinking!

*** Coming Soon!!!
I have a new book being released on April 3rdand just for the heck of it, I went to see whether there’s a way to set up a pre-order button for my readers so they can be notified when the book has finally been released. It would act as a reminder to anyone reading my series that the newest segment is ready for purchase.
Right???
Makes sense to me.
Of course, I went on Google to find my answer and was rather disappointed. What I found on Amazon was that if you were hooked with a big-name publisher, then yes, pre-orders were available. But sadly, for the independent authors – not so much.
I guess there is a convoluted way around this dilemma explained by a fellow author on the Kindle Direct Publishing page https://kdp.amazon.com/community/message.jspa?messageID=331672who set up a cover, a welcome note, and instructions for getting the full ebook when it became available. But this didn’t sound like the best solution for me. Unless readers were aware of this being done, I can’t imagine most folks going along with paying for a book and having to wait for it to be released.
Besides, I wasn’t really thinking that money should be paid up front, more along the lines of our fans being able to fill in some type of notification form. For instance, as soon as the book written by Mimi Barbour is released with the specific title of High Stakes Gamble then the people who filled in the request would be automatically sent a notice with a nice BIG link or buy button.
Doesn’t that make sense?? Wished Amazon thought so.
Oh well! I guess if an author is really well organized, he/she could put up a pre-order list where fans can sign up on their website or blog to be notified when the book is released. Maybe they could offer the reader a discount on the first few days before setting the proper price to be charged.
Wouldn’t work too well for me since I charge 99cents for all my books…..grumble!! But the notification list for them to sign might not be a bad idea.
Have any of you tried different methods to get around this problem? Please share J
