It's up to you to setup shipping profiles and to decide on shipping rates.
You can start with your local postal office and see what their shipping rates are.
Also research other couriers and see which ones offer better rates locally and internationally.
Check other similar stores from your area and see what they are charging for shipping.
You can also chat with other sellers about how they decided on shipping rates on forum. There were a few discussions about it in the past.
