多谢MM的建议。我仔细看了在slickdeal上的分析，发现这个卡基本不会影响credit，因为这个是Business的卡，和个人卡对credit的影响是不同的，这是从FAQ里来copy来的”Does this affect my credit score? Not in the traditional way. You may
take a 2-4 point hit for a few months for the inquiry but the key here
is that cancelling your card will not show on your credit report and
there are no long term ill effects.“

麻烦点的地方好像就是去打电话了。不过为了$250也是比较值了，毕竟Chase 的promotion不是总有的。而且每个人只能申请一次好像，这个好像可以申请多个呢。
