In the context of children's books, the net price refers to the total cost a buyer incurs after all applicable discounts, rebates, or promotions have been deducted from the retail price. This figure is crucial for publishers and retailers as it directly affects profit margins. For example, while a book might have a list price of $20, after a 20% discount, the net price would be $16. This information helps parents, educators, and librarians understand the actual cost involved in acquiring literature for children.
