First of all, the book must be genuine, so you must book a franchise store. Secondly, the cost of books is actually very low, but in the past, the cost of physical bookstores was higher, so in people's impression, books are genuine only if they are expensive. Now the emergence of online stores such as Taobao has reduced the cost and made people feel that books are very cheap. In short, if it is not genuine, the author will not get any benefits! Why is it so cheap? Because of mass production, the cost is reduced and the quality is poor, so it is cheap. Of course, genuine books are good and expensive. Many people want to support them, but they can't. Of course, being so expensive also tells us that genuine books are profiteering.
