結果剛剛收到回覆竟然被拒絕 "I'm really sorry for the inconvenience as your recent purchase does not qualify for a price adjustment because a coupon had already been applied to it. I’m sorry we're unable to process your request." 找了客服argue using a coupon isn't in the price adjustment restriction 如果要退貨再重訂不符合經濟效益 第一個罐頭回覆拒絕 第二個就給退了 供大家參考
