Kiss for a pound? (7)
I believe the answer is:
smacker
I believe this clue is a double definition.
'kiss' is the first definition.
(smacker is a kind of kiss)
'a pound?' is the second definition.
(I've seen this before)
'for' is the link.
(Other definitions for smacker that I've seen before include "pound" , "Loud kiss - GBP1" , "Loud kiss -- PS1" , "someone taking part in strike?" .)
