Cost of your key chipset is around 2.4 to 2.5 US. At $5.00 you are making a lot of money. I do not think we can accept cost increasing. We pay $3.45 for full size optical mouse today from your competitor. Your company is getting a premium for this product.

We understand your concern and position but please also understand our concern and position. I believe that you fully understand that we are not only a material supplier but a mouse manufacturer instead of a material supplier. Therefore, the US$5.00 cost we offered including includes the cost of our labor and all necessary materials. When you change the design of the color box, an extra US$0.2 cost will be charged by our box supplier.

Plastics cost ,nowadays, has is100% increased but we have not raised the unit price for this reason. In fact, not only our company is not making any profit, but also " Mary" is not gaining bonus from this.

However, based basing on our partnership, we are always trying our best to support you, therefore, Therefore, we look forward to get getting your possitive reply. Please accept to share the additional US$0.1 for the changing of color box.

Best Regards,
Mary
