Price to enter publicity campaign? (9)

Ross

I believe the answer is:

admission

'price to enter' is the definition.
(cost of admission)

'publicity campaign?' is the wordplay.
'publicity' becomes 'ad' (short for advert).
'campaign?' becomes 'mission' (campaign can mean a task or mission).
'ad'+'mission'='ADMISSION'

(Other definitions for admission that I've seen before include "Disclosure" , "entry charge" , "guilty revelation" , "Ticket holders expect this" , "Entrance fee" .)

I've seen this clue in The Times.
