Cut producing bargain (4)
I believe the answer is:
snip
This clue is a double definition.
'cut' is the first definition.
(snip is a kind of cut)
'bargain' is the second definition.
(slang term for a good deal)
'producing' is the link.
(Other definitions for snip that I've seen before include "Cut back" , "Cut - prune" , "nick)" , "Cut off a small bit" , "Surprisingly cheap item" .)
