Hi,
Generally setting up account is possible only once you start doing good no of transactions with a specific courier.
DTDC is good and reasonable.
Also initially depending on the item and buyers area you will be charged differently.
e.g. This item of yours is charged 150 for a particular place but will be charged 120 or 100 to other places depending on the item, packing and weight.
This is a lesson and slowly you will get a hang of these charges.
