Frugal, thrifty (10)
I believe the answer is:
economical
I believe this clue is a double definition.
'frugal' is the first definition.
(synonyms)
'thrifty' is the second definition.

(Other definitions for economical that I've seen before include "Money-saving" , "Using little" , "Giving good value for money" , "Reasonable" , "Providing good value" .)
