"Books purchased in this bookstore will not be returned without quality problems" is the overlord clause?

Usually, domestic retail industries, such as supermarkets, department stores and bookstores, have similar terms of no return without quality problems. This clause does not clearly determine whether it is a overlord clause in national laws, so it is difficult to say. Of course, judging from the other party's feedback on your service, it is really poor, at least unreasonable, and the professional quality is not high.

If you are really angry, I suggest you start from the top, "The book will be my property after it is sold. Why did the clerk stamp my book without my permission? Do I have the right to change books? " Make an issue of this point, I think your reason is tenable, although it breaks the rules of bookstore sales. Because you want to buy a brand-new book, not a stamped "destroyed" book.

In this kind of dispute, look for the bookstore manager or the floor manager, not the ordinary clerk. The clerk has no right to promise whether it can be returned, and it is fruitless to argue with them. The key to complaining is to find the right person.

If you are angry and don't want to toss, forget it. Be careful next time.
