8 同意还盘
3句英文任你选
I'll respond to your counter-offer by reducing our price by five Yuan.
我同意你们的还价，减价5元。
To meet your requirements, we would like to reduce our price by 2%, which, I hope, will be satisfactory to you.
为满足你方要求，我们愿降价2%，希望能令你方满意。
Let me make you a special offer.
我给您一个特别优惠价。

半个句型要记牢
reduce one's price by -(降价……)

Tip:
降价用 reduce，抬价用 increase。降价的幅度用介词句，到达某个价格用 to。另外，补充一些价格术语: cost price (成本价)， market price (市场价), retail price (零售价), wholesale price (批发价)。
