I think it is one of the companies with the best customer service in the world, a pity that its content is sometimes not so good since many times there are manipulations due to Amazon's own advertising policy. The results of amazon are often not the indicated or ideal for the client since it prioritizes the bid of those who sell to the real search or need of those who buy. This is its biggest cons.
I think amazon should start prioritizing organic searches and not so much ads, since in the medium long term this will bring them many problems and the platform will no longer be as good and reliable as it has been.
