COD charges will be based on the fix rate or percentage fee set by the courier, and will be deducted directly from the COD amount set by you. For example, if you book J&T Express to ship your parcel at the COD amount of S$100:-
J&T Express COD charges of SGD2 or 3%, whichever is higher:
SGD100 x 3% = SGD3
As SGD3 is the higher COD charges, this amount will be deducted directly from SGD100 when you request to withdraw your COD amount from the ‘COD Settlement‘ page.
