I often use AI to help me polish the content I communicate with customers, here is what I wrote:
For sample production, you will need 100-200 bags of each design for filling tests. I have already applied for the maximum discount with our manager; you will not need to bear the material costs, you only need to pay the sample fee. The sample fee for each design is US$250, while we normally charge US$300 per design. We look forward to your suggestions.
