As mentioned to you, we are sharing the different based on my costing to you as a matter of goodwill.
We are also taking care of our own freight charges.
80 cart of 400ml = 32 lit
Costing for 19 lit pail is US$553.50, therefore 32 lit costing is US$553.50 / 19 x 32 = US$932.21
Costing for 80 cart of 400 ml = US$31.75 x 80 = US$2’540
Different is US$2’540 – US$932.21 = US$1’607.79
Therefore my share should be only US$1607.79 / 2 = US$803.90
I will also need your Delivery Order with customer stamp for receiving the 80 cartridge. Once this is in, Angeline will issue the credit note.
Hope you will understand.
