I often buy classic books but want a particular edition which might include specific notes or a translation by a specific writer, but following the Amazon search - actually clicking on a link where I’ve constructed the search with meticulous attention to the terms that are essential to me - will often lead to a totally random result from an unknown ‘publisher’ which meets none of my criteria and wasn’t the link that was presented to me.
Obviously all the reviews are bunched haphazardly together - including the ones that praise the translation which the presented book doesn’t include, and the ones warning about poor formatting from the pirated edition.
If Amazon can’t even sell Kindle titles without commingling, then it blows my mind people buying electronics from them.
