Unfortunately, once an order is placed, we are unable to alter the order or change the shipping method.
In some cases, it may be possible for us to cancel the order so that you can place a new order. We make every effort to send orders out quickly from the Science Buddies Store so that your student can get started on her science project. This means orders are processed shortly after they are placed. If your order has already been processed for shipping, the order cannot be canceled.
