Mailing cost (7)

Ross

I believe the answer is:

postage

'mailing cost' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for postage that I've seen before include "It could be first-class" , "Cost of corresponding" , "Money charged for delivery" , "Amount paid to mail" , "Cost of sending letter" .)

I've seen this clue in The Sun and the King Feature Syndicate.
