The most reliable channel is often the most expensive. In order to protect the interests of agents and retail stores, the price of flagship stores is basically synchronized with that of physical stores. However, these official flagship stores will launch holiday promotions and new product promotions during the online shopping festival, which is still a bit strong. The words "JD.COM is self-employed". COM "is written for the convenience of understanding, and there is nothing wrong with replacing these large e-commerce platforms with" Amazon self-operated "and" Togo ". (Amazon and Togo are recommended first, and JD.COM is generally indicated in the comment area. The self-management of COM is not reliable. Due to the huge shipment, the large e-commerce platform has a low cost advantage, small profits but quick turnover, and the sales price will be significantly lower than that of the physical store, with high cost performance. However, it should be noted that although these big platforms can basically guarantee the real goods, the oil brands they sell are also mixed. These "miscellaneous brands" often promote various preferential activities, so we should pay attention to choosing reliable big brands. As for JD. COM is not self-operated, which is no different from the ordinary merchants of Tmall. Judging from this file, it is my "no novice try" area, and the "Taobao seller" behind it is relatively more unreliable.
