What Does It Take to Be a ‘Best-Selling Author’? $3 and 5 Minutes
To everybody who saying something along lines "amazon should do X Y Z": amazon's business is clusterfuck, but profitable one. They have TONS of issues with ranking, process, UI, etc,etc,etc. Almost every single problem requires reaching through seller support to engineering team, or someone having closer DB access. Categorization, fields are all SUBcategory-depending. The way you get included into certain categories is also depends on product/subcategory. Stuff sometimes simply doesn't work. In 2015 alone they switched between three different promotion offerings.I am selling on amazon and deal with it often :) It looks like it is constant growing pains.
