问题：我有个土耳其的客户新客户，没有合作过，对我们价格挺满意，差不多2万美金 吧，但是就是模具费不愿意出，我用了你的满多少金额然后给返还给他，他也不同意，你能 帮我想想办法吗？
We really appreciated that you can put your best understanding on our module fee, because you understand that our engineers need to spend lots of time to confirm with hardware company (module factory) and even software company (check everything whether match well). We spent all the day to confirm it, fortunately everything all for you want to.
Up to now, we met all your requirement, in order to save process time and confirm correct sample order, could you please pay US$500-US$1000 as sincerity deposit for customized requirement, then, our engineer can pay much more attention or time on this case, and our whole team can continue to discuss during February, 2021. This amount just keep in our account, when your order was placed one day, then remove it.
Hope you can understand, it is just a method that increase mutual trust. We will have no reservations, and the engineer also try best.
Thank you so much.
