Let’s not even discuss how terrible Amazon’s search engine is; frequently the search gets spammed by ‘sponsored’ products and ‘we thought you might like this’ to the point of completely obscuring your original objective. I was trying to buy the most recent book by a particular author, but it was more than halfway down the first page of search results, despite searching for that author and ‘Publication date: most recent’.
eta: Amazon is not the only online sales giant guilty of this; ebay’s Cortana is just as horrible.
