Some price deduction granted (5)
I believe the answer is:
ceded
'granted' is the definition.
('cede' can be a synonym of 'grant')
'some price deduction' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'CEDED' is hidden within 'price deduction'.
(Other definitions for ceded that I've seen before include "Yielded, surrendered" , "Given up" , "'Yielded, gave way (5)'" , "Relinquished" , "Gave up (power)" .)
