Prices from low to high (except activities): Tmall/Dangdang, Amazon and JD.COM are self-operated.

Recommended delivery speed: Amazon and JD.COM are self-operated.

Second-hand recommendation (good quality and low price): turn around.

Comprehensive recommendation: Amazon, JD.COM, Tmall flagship store, Dangdang.

Special recommendation here is to look around. It is a second-hand trading platform. Some time ago, the activity of buying second-hand books became hot, and then the book transfer section was launched. I buy books through this channel.

Advantages: the price is cheap, and it is found that there is plastic packaging after getting it. After unpacking, it is basically not a second-hand book, and there are no obvious traces of use (hooks, paintings, defects), and the paper quality is also very good.

Disadvantages: books are out of stock and new books are basically not available. After all, it is a second-hand book, so it is inevitable. If you don't care much about whether it is a first-hand book, I suggest buying it.

Amazon's books can be said to be authentic, reasonably priced and not particularly expensive compared with many platforms. Logistics is also Amazon's own, and it is also well received on the Internet. Secondly, JD.COM, when buying, you should choose a self-operated bookstore or a bookstore that you think is more reliable, but its unit price is generally more expensive. If you catch up with the event, I recommend you buy it, JD. The logistics of COM is also well known.

In order to reduce the probability of piracy, the flagship stores of Tmall's major bookstores did not involve Taobao. Even in the flagship store, there will be a certain probability of pirated books, but at most some papers will be too thin. Dangdang, personally, it is still worth recommending. Buying genuine books through this channel can ensure that netizens generally report cases of violent express delivery. In fact, this is inevitable, and the price is as cheap as Tmall.
