The delivery time of Amazon pre-sale products is determined by the pre-sale time on the product, and the specific time depends on the manufacturer's production and supply chain. Amazon usually indicates the estimated delivery time on the product page, but this is only an estimate, and the actual delivery time may be delayed. If the product you purchased is in pre-sale status, it is recommended that you wait patiently for the delivery notification and pay attention to the order status in a timely manner. If you have any questions or problems, you can always contact Amazon customer service for help.
