直接杀价：
　 That is unreasonable!I'd take it for 100yuan.
  这真是卖的太贵了。如果100元，我就买。
　How about 100元？
　卖100元如何？
　I'd buy this if it were cheaper.
  再便宜一点我就买。　

拐弯抹角地杀：
　 Lower the price,and I'll consider it.
  价格低一点，我才会考虑。
　It's a little overpriced.
  这标价有点贵。
　I like everything about it except price.
  这东西除了标价之外，我都喜欢。

尔虞我诈地杀：
　 I have seen this cheaper (in) other places.
  我杂别家有看到过更便宜的。
　I heard other stores were having great mark-downs onthisitem.
　听说别家这个东西在大减价。
　If I buy more than one,will you give me a discount?
  多买一点有折扣吗？

我不会杀价。更何况用英文
