Get money for chips produced by unreliable chains (4,2)
I believe the answer is:
cash in
'get money for chips produced' is the definition.
I can't tell whether this defines the answer.
'unreliable chains' is the wordplay.
'unreliable' is an anagram indicator.
'chains' with letters rearranged gives 'CASH IN'.
'by' is the link.
Can you help me to learn more?
(Other definitions for cash in that I've seen before include "what piggy bank has?" , "Take advantage of" , "Exchange for money; seize an advantage" , "Realise" , "Make money" .)
