Price includes a shoreline (5)
I believe the answer is:
coast
'shoreline' is the definition.
(I've seen this in another clue)
'price includes a' is the wordplay.
'price' becomes 'cost' (synonyms).
'includes' indicates putting letters inside.
'cost' going around 'a' is 'COAST'.
(Other definitions for coast that I've seen before include "float" , "Make no effort" , "Run without power" , "Littoral region" , "that goes all around the UK?" .)
