I totally get the frustration and such, and not trying to protect Amazon, but: author's web site intercepting browser history to trigger "checkout this content before you leave" when back navigation is clicked is outright evil. Just don't do that, be kind to visitors.

Edit:

1. Dictionary: evil, adj.: morally bad, cruel, or very unpleasant

2. To get the prompt you need to stay around on the page for a while, scroll around, pretend to read it. Triggers at least in mobile chrome browser.
