Price covering a cruise (5)
I believe the answer is:
coast
'cruise' is the definition.
(I've seen this before)
'price covering a' is the wordplay.
'price' becomes 'cost' (synonyms).
'covering' means one lot of letters goes inside another.
'cost' enclosing 'a' is 'COAST'.
(Other definitions for coast that I've seen before include "float" , "(Of vehicle) move without using power" , "Run without power" , "Diminish, lessen" , "Freewheel - seashore" .)
