Bearing cost of transportation (8)
I believe the answer is:
carriage
This clue might be a double definition.
'bearing' is the first definition.
(someone's stance or posture)
'cost of transportation' is the second definition.
'carriage' can be an answer for 'transportation' (I've seen this before). I'm not sure about the 'cost of' bit.
Can you help me to learn more?
(Other definitions for carriage that I've seen before include "Transportation" , "Section of a train" , "Coach - bearing" , "Railway vehicle" , "Buggy" .)
