There may be a start-up idea here: an application to allow authors to easily monitor changes to their ebook prices?

This is one of those examples where yes, that sounds like a good idea but the size of the addressable market is rather slim.

Most self-publishers are not making huge amounts of money to justify spending more than a token amount on such monitoring.

A bigger app/suite of services to support self-publishers (especially as many are not tech-savvy) might be helpful, which could include this.

That's not the problem here. The author presumably found the price change rather quickly. It was Amazon that took a long time to respond to the error that's at issue.

Sounds more like a feature in a bigger app, but yes, I agree with you. There's something there.

The app should be able to easily post your book to most major ebook markets.
