直接殺價：

That's unreasonable! I'd take it for (100￥.)
這真是賣得太貴了！如果（一百塊）我就買。

How about (100￥)?

賣（一百塊錢）如何？

I'd buy this if it were cheaper.

拐彎抹角地殺：

Lower the price, and I'll consider it.

價錢低一點我才會考慮。

It's a little overpriced.

這標價有點貴。

I like everything about it except the price.

這東西除了價錢之外我都喜歡。

爾虞我詐地殺：

I've seen this cheaper (in) other places.

我在別家有看過更便宜的。

I heard other stores were having great mark-downs on this item.

聽說別家的這個東西在大減價。

If I buy more than one, will you give me a discount?

多買一點有折扣嗎？
