Fed poorly no more, somehow getting easy cash (5,3,3,4)
I believe the answer is:
money for old rope
'easy cash' is the definition.
'fed poorly no more somehow' is the wordplay.
'somehow' indicates anagramming the letters.
'fed'+'poorly'+'no'+'more'='fedpoorlynomore'
'fedpoorlynomore' is an anagram of 'MONEY FOR OLD ROPE'.
'getting' is the link.
(Other definitions for money for old rope that I've seen before include "A piece of cake" , "An easy job" , "Profit for little effort" , "dealing with elderly guys?" , "Easy profit" .)
