導(dǎo)購口語:

This is sale price. We earn very little in this line of goods.
這是最低價了，這類貨品的利潤很低。
We are practically giving this away. It's almost the cost price.
我們簡直是在把這送人了。這差不多是成本價了。
This is the rock bottom price and any further reduction is out of the question.
這是最低價格，無法進一步降價。

語句解析:

This is the rock bottom price…這個是最低價格……
the rock bottom price = the lowest price 最低價，如果對方還不相信，你可以在補充道：You get a chance like this only once in a blue moon.（這可是千載難逢的機會啊。）我們都沒見過這樣的月亮，按照天文學(xué)家的說法，月亮不可能是藍色的，至少這也是千載難逢的天象。所以once in a blue moon意思就是“千載難逢”。

情景再現(xiàn):

This is our rock-bottom price; we can't afford to make more reduction.
這是我們的最低價了，不能再降了。
We can't come down any more. But you'll get a free gift if you spend up to two hundred yuan.
我們不能再減了，但是如果消費滿200元，您就可以得到一個贈品。
