As for whether the price is reasonable or not, or whether it can be accepted, it is estimated that it depends on whether the landlord really likes the book. It is really hard to say.
In addition, the landlord should pay attention to whether this book is genuine or not when collecting it. Some big books are pirated, and I personally resolutely resist them.
In addition, after some books are sold out, the original author may publish an electronic version online, and the landlord can try it.
