Amazon is an online retail and financing company. The products are much cheaper than other places because they need short-term financing. So low prices can attract consumers and make it easier to raise funds.

Amazon's directly-operated stores will pay the supply channel for the products sold in a week because they have to use the funds raised for other projects within a week... It is true that many things on Amazon are cheaper, but not much different. The only difference is that the website is not as good as JD.com, and the product pictures and comments are not as good as JD.com. But the products are real, no problem, at least I have never bought fakes, and the products are relatively cheap. It is not a question of how much you lose or how much you gain, but how much you gain.
