Bargain; cut (4)
I believe the answer is:
snip
I believe this is a double definition.
'bargain' is the first definition.
(slang term for a good deal)
'cut' is the second definition.
(I know that snip is a type of cut)
(Other definitions for snip that I've seen before include "Steal" , "Bargain (informal)" , "Cut - price bargain" , "Cut with shears" , "Trim, clip" .)
