After time sees delivery charges (7)
I believe the answer is:
postage
'sees delivery charges' is the definition.
I can't tell whether this definition defines the answer.
'after time' is the wordplay.
'after' becomes 'post' (suffix meaning after, eg post-war).
'time' becomes 'age' (an age is a period of time).
'post'+'age'='POSTAGE'
Can you help me to learn more?
(Other definitions for postage that I've seen before include "Delivery cost" , "Cost of corresponding" , "Cost to send a mail item" , "Amount paid to mail" , "Money charged for delivery" .)
