Let me reiterate, if you guarantee a minimum order, the discount is higher.

让我重申一下,如果你保证最低订购量,折扣更高。

We understand, but we have to consider realistic expectations of our market.

我们理解,但是我们不得不考虑我们的市场的现实期望。

What would be the minimum acceptable order to receive an 8.5% discount on the total order?

总订单折扣若为8.5%，那么贵方能接受的最低订购量为多少?

We'd be willing to offer that kind of discount...

我们愿意提供这样的折扣…

...with the proviso that your company guaranteed an order of 800 units.

…条件是贵公司保证800套订单。

I think our company could go along with that.

我认为我们公司也可以接受。

Then, do we have a deal?

那么，可以成交了吗?
