Dear Sir,
Our quantity of order will increase gradually. Meanwhile, I am much concerned as your probable 75% discount for others' order will affect our sales. Could you offer us some guarantee? As the cooperation has been fluent before, it will surely continue. As our communication has been through a year and you have offered us great support, we sincerely show our thankfulness to you.

希望能帮到你！

Dear Mr./Ms.~或者直接英文名，因为是经常联系的，不需要叫xx先生，否则较生疏
We will place more and more orders for you in the future. But meanwhile, we have some concerns that if other customers in China buy goods from you, you will also provide 75% discount, which will influence our sales performance. So could u pls give us some guarantees? We've had a great cooperation all the time, and this good relationship will be well kept continuously. Thanks so much for your great help on me in the past one year.

个人认为：老外可能不太认同您的观点，因为当心竞争对手的介入而影响您的销售业绩。
我建议您：给老外一个选择： 比如说我1年买10K ，7.5折，
15K 7.0折 这要可能会更有吸引力
