Light novels are a type of literary work that is usually printed and published by Japanese publishing houses. Since light novels were usually printed by small publishing houses, the price would vary. In addition, because online sales channels did not have inventory management and rental costs like traditional bookstores, the price of buying genuine light novels online was often higher than that of physical bookstores. In addition, online purchases could also enjoy more convenient delivery and after-sales service, which was one of the reasons why the price was higher than the fixed price.
