Dear xxx
Regarding to the issue of unit price of the order number 06-333.
Please kindly note that the original price of US$3.0/pc is the price of model sc001. However, it is changed to sc002 as per your requested in the later stage which the price of sc002 is US$5.0/pc.
The final item you have ordered is sc002 NOT sc001, it is therefore the unit price shown on the invoice is US$5.0/pc in stead of US$3.0/pc.
Trust it is clear now.
Best regards
