Among these e-commerce companies in China, Amazon is considered to be a relatively formal one. There should be no problem with the goods, and the authentic ones are for sure (but third-party sellers are not guaranteed).

In terms of logistics and packaging, it is the best in the country. Except for books, which do not need excessive protection, plastic bags are used, and the rest are packed with air shock-absorbing bags and cartons.

The delivery speed is basically within 24 hours, but sometimes it is displayed very slowly because the goods may be transferred from a warehouse in another place, which takes some time.

The logistics company uses a cheaper local logistics company, but you can pay cash on delivery, and you can pay after inspection. Compared with other e-commerce companies, Amazon, JD.com, Dangdang and other well-known e-commerce companies are reliable, and returns and exchanges are very convenient. You only need to submit a return application, and a staff will come to pick up the goods to be returned and exchanged. If the conditions are met, you can return and exchange (except for some special items such as food, so if you buy such goods, you should inspect the goods first and then sign for them after payment).

However, Taobao is an exception. Taobao is a business model similar to street stalls, and there is no guarantee that the sellers therein will not commit fraud, etc. However, sellers with good reputations can be purchased.
