Bearing the cost of sending goods (8)
I believe the answer is:
carriage
'bearing' is the definition.
(someone's stance or posture)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for carriage that I've seen before include "Engine- or horse-drawn vehicle" , "Section of a train" , "Posture or train compartment" , "Bearing, deportment" , "Railway vehicle" .)
