The bargain store's profits? (5)
I believe the answer is:
gains
'profits?' is the definition.
('gain' can be a synonym of 'profit')
'the bargain store's' is the wordplay.
'GAINS' is hidden within the letters.
But, I am uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for gains that I've seen before include "Profits" , "Wins" , "Narrows the gap" .)
