卖了个东西，买家回复：
I just paid for the Nexus via eCheck from my bank account. The payment shoul
d go through in a matter of three business days. The only problem is its a g
ift for my father on Wednesday. I just really need it ASAP without delays. I
'd really appreciate it if you could help me out. Let me know. I await your
response. Thanks.
我是肯定不会没收到钱寄东西出去的，请问我应该怎么回复呢？我可以跟买家说我必须
等echeck clear了才付钱，如果他等不及的话请去cancel order？这样会违反ebay的规
章吗？之后我还可以给second-highest的人offer吗？
菜鸟卖点用过的nexus 7，没想到碰到这种事，请大牛指教。
