Moreover, there are now very fews company that produce CV cups. We have raised the prices for other customers, but still offer you a low price in view of the long-term cooperation between the two companies. I would appreciate it if you could accept the offer with consideration of the difficulties on our side.

We are considering the good relationship between us and offered such a good price to your company, we hope taht it could be in line with your requirement and also look forward tos eeing your valuable order soon.
