Dangdang is just a platform. It has its own business account book, called self-operated account book. After the conditions are met, it can be mailed on 29 and 59.

However, Dangdang has also opened some channels to sell books to other people or bookstores of other businesses. Buy books in these areas that are not operated by Dangdang, and determine the freight/delivery time/delivery place according to the store rules formulated by its own merchants.

The page of each book is marked with whether the book is self-operated and which company delivered it.
