I want to add the fact, if I may, that what is now directing a lot of attention to Amazon is the so-called box that you see on the upper-left corner with the recommendation. There are also allegations and some evidence that merchants have to do fulfillment by Amazon to come up high in the rankings in the box. Amazon extends and leverages its power on the platform to get some extra commitment from the merchants. Namely, the price to pay to be high up in the box that gives you the first choice in the click box, as it is called, is that the fulfillment will be done by Amazon.
