Let me see if I have this correct.

让我看看，这是否正确。

From your point of view, it's more important to order the units you need...

从你的观点来看，订购你所需要的数量会更加重要…

...rather than to get the cheapest price.

…而不是以最便宜的价格。

Right.

是这样。

Most importantly, we don't want to keep a lot of back stock...

更重要的是，我们并不想积压太多库存。

...and we're prepared to suffer a slight increase in cost for orders if necessary.

…并且必要时，我们准备略微增加订单成本。

Then, may I suggest an alternative proposal.

然后，我建议另一个提议。

With your past orders ranging between 600 and 800 units,...

你过去的订单量在600套到800套之间，…

...I would propose setting the discount rate 3% lower.

我提议将折现率降低3%。

Would you be willing to accept that?

你愿意接受吗?

Before I respond to that offer, let me do a few calculations of my own.

在我回复报价之前，让我自己做一些计算。
