刚来的时候不懂事，申请了好多store card，基本上都只用了第一次，怎么办呢？是cancel好还是放在那儿不管它们？大家给出出主意吧！叩谢！

I read from MSN money that you better only keep one store credit card for your favorite store. Get the initial discount and cancel the new ones right away which is good to prevent harm on your credit score while you can enjoy the discount. But be aware that every new card usually can deduct 20 points from your credit score.

太感谢了，这就着手cancel
