A conveyance or what one pays for it (8)
I believe the answer is:
carriage
'a conveyance' is the definition.
(I know that carriage is a type of horse-drawn vehicle)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for carriage that I've seen before include "Bearing; part of train" , "Conveyance, its cost" , "Coach - bearing" , "Bodily posture or wheeled vehicle" , "Bearing, deportment" .)
