After you placed an order, your order begins to process. Once order is placed, you can no longer change the size/quantity/color/ or add other item/s or change the mode of payment but you can definitely request to remove the item or cancel your order to place a whole new one. To change or cancel your order prior to shipment, you must contact customer care at email@example.com
Please note that most orders process quickly and can enter the shipping process within 24 hours. If your order has already entered the shipping process, it cannot be changed or cancelled.
