A very interesting read on the war being waged between sellers on what has become the biggest marketplace in the world.
The article is extensive and thorough and will take about an hour to read depending on your reading speed, be warned.
As a consumer, I use amazon especially for work-related orders, not so much for personal orders.
I do try to use it sparingly so as to not add too much importance to a tax-evading-monopoly that already has more than enough market share but i find it increasingly difficult to resist the convenience ordering on amazon proposes.
Reading this article has given me insight on some dealings amongst sellers that I was not aware existed and has definitely changed my future approach while searching on their platform.
