There’s a lot of reasons why Amazon Sellers decide that they don’t want to sell on Amazon anymore. Maybe they couldn’t make it work or maybe they just put a lot of time and capital in it for very little profits and it’s just not worth your time or capital anymore.
Selling on Amazon can be really competitive and it takes a lot of capital investment and sometimes it just doesn’t make sense to just keep doing it and that’s okay because a lot of times you don’t find that out.
