It's gotten ridiculous in the last month with behavior I've never seen before. If I want to buy a specific book I type <author name> <title> into the search bar. The search bar even helps me complete the entry, and then a page shows with a choice of several books with my chosen book at the top.

Fine. Except now after one second, the whole page changes and then there's only one book on the page and it has nothing to do with the book I actually searched for.

So obviously they know about the book I want because they just showed it to me but then they make it disappear in favor of one I don't want but which I presume is one the publisher paid them to show me.

My workaround is to search on Amazon in a private tab so they don't know who I am. In that case the book I want shows up and I can click on it and get its URL and then paste it into the original Amazon window where I'm already logged in, and I can order it. Except I don't, because I'm so disgusted by this I go directly to the publisher's website and order it there.

This is ridiculous.

Amazon is throwing money on the floor with this behavior and they're probably just begging for a restraint of trade class-action lawsuit.
