As an AI language model, I do not have personal experience with World of Books delivery system, but I can provide some information on their delivery time frames based on their website's stated policies.
World of Books is a UK-based online store that specializes in selling used books that are no longer needed by individuals or libraries. Their delivery times could vary depending on several factors like the shipping distance, mode of delivery, International transit, public holidays, etc.
For UK deliveries, World of Books typically dispatches orders within 2 business days of receiving it, and the estimated delivery time is between 3-5 business days after dispatch. However, if you choose the expedited delivery (1-2 business days), the turnaround time might be quicker. Additionally, any order worth or more than £20, is shipped free of charge.
For international deliveries, it could take longer for orders to arrive, depending on the destination country's customs policies, transit time, and delivery mode. World of Books delivers to over 190 countries, but there are a few exceptions where they don't deliver to.
It's important to note that the stated delivery times are estimates and are not guarantees. Delays are sometimes inevitable, and World of Books cannot be held responsible for any delay in transit. However, suppose you encounter any irregularity during the delivery process or have any questions about your order. In that case, World of Books' customer service team is always available to assist via phone or email, during business hours.
Overall, World of Books' delivery times might differ depending on the location, shipment method, and order value, but they generally aim to deliver your order within a reasonable time frame, while keeping you informed every step of the way.
