I keep shipping fee's to a minimum. In the US it is free shipping unless the customer requests another choice.
I have had to increase some of my international fee's as the basic flat rate shipping does not allow tracking any longer and there is no guarantee the products will arrive safely.
Most of the time, I pay a percentage of the shipping. If your shipping fee is substantially less , I will credit back the difference.
As in many sites, I do not make money on the shipping fee's
