If you want to combine two orders, please open a support ticket
If the second order is placed within 12 hours after the first order, we will ship them out the next day. If the new order is placed more than 12 hours after the first order, we CANNOT guarantee to combine them. The earlier order might get shipped already.
Since we try to ship orders out within 24 hours, sometimes your request arrives "too late". We cannot guarantee the result.
