Once an order is placed with ItsHot.com, the ability to upgrade the shipping method will depend on the order status and the specific policies of ItsHot. Typically, if the order has not yet been dispatched, there may be an option to modify the shipping choices. However, if the order is already in the process of being shipped, it is unlikely that changes can be made. Customers are encouraged to check the order confirmation details on the ItsHot website, as they often provide information regarding order modifications and shipping options. If there are any specific questions or concerns regarding shipping or order changes, the customer may find relevant information on the website's customer service section.
