求翻译：美国和中国的时差我也弄不清楚怎么计算，总之上述情况就是我这三个订单的真实情况。这些商品是否需要我自己操作重新选购？这三个订单我只需等待就能发货了吗？如果重新选购以后，是否会造成重复扣款呢？期待您的答复，谢谢。是什么意思？

United States and China, the difference I am not sure how, but this is my reality of the three orders. Need my own actions back to buy these goods? The three orders: I only need to wait for shipping? If after purchasing, is it will create a duplicate request for? Looking forward to your reply, thank
