Cut a bargain (4)
I believe the answer is:
snip
I believe this clue is a double definition.
'cut' is the first definition.
(snip is a kind of cut)
'a bargain' is the second definition.
(slang term for a good deal)
(Other definitions for snip that I've seen before include "Cut - certainty" , "Cut off a small bit" , "Surprisingly cheap item" , "Cut - price bargain" , "Quick cut - something easily done" .)
