********** huge amount for customs ,for a minor order

I recently bought from shein online clothing and I think its about time shein must be transparent about the customs duty and transport cost before we take final decision to make an payment for the order . buffalo charges abnormal fees ,its for the first time paying such a huge amount for a minor order and it was not worth paying that amount ,I wont order from shein again .I was amazed by the custom duty it was just rediculous.......ripped of such money was so unbelievable
