Shipping cost refers to the fee charged for sending children's books from the seller to the buyer. This cost can vary based on factors such as the shipping method chosen (standard, expedited, etc.), the weight and size of the books, and the destination. Some retailers may offer free shipping on orders over a certain amount or provide flat-rate shipping, making it easier for parents and caregivers to purchase books without worrying about fluctuating costs. Understanding shipping costs is essential for budget-conscious readers and educators looking to expand their collections affordably.
