Bargain crop (4)
I believe the answer is:
snip
This clue is a double definition.
'bargain' is the first definition.
(slang term for a good deal)
'crop' is the second definition.
('snip' can be a synonym of 'crop')
(Other definitions for snip that I've seen before include "Quick cut - something easily done" , "Steal" , "nick)" , "Surprisingly cheap item" , "Bargain - crop" .)
