お手数ですがorderAとorderBのPayPal請求を分けてもらえますか?発送は一緒で構いません。それと先日返品したXの代金$40を今回の代金から引いてもらえると助かります。
Is it possible that I pay each order A payment and order B payment separately by PayPal? It is OK that you
can ship both order together. And, I'd appreciate if you could subtract $40 for the recent returned product from payment this time.
