Penny-pinch (6)
I believe the answer is:
scrimp
'penny-pinch' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for scrimp that I've seen before include "Be prudent" , "Be thrifty and parsimonious" , "Skimp, stint" , "To pinch pennies" , "Pinch and save" .)
