To ensure the smooth running of our order system, we regret to inform you that we are unable to make any changes to orders once they have been placed. If you wish to make additions or modifications to your order, kindly reach out to us to cancel the existing order so that you may place a new one with the desired changes. Alternatively, if it has only been a few minutes since placing the order, you can cancel it directly from the "My Account" page. However, if this option is no longer available, please contact us immediately to request cancellation. Please note that once an order has entered the processing stage in our warehouse and is being prepared for shipping, cancellation is no longer possible.
