Add it up for middlemen, as graduate grows disheartened, supplying cloth sacks (4,4)
I believe the answer is:
tote bags
'middlemen as graduate grows disheartened supplying cloth sacks' is the definition.
I can't tell whether this defines the answer.
'add it up' is the wordplay.
'add' becomes 'tot' (synonyms).
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'up' becomes 'bags' (I can't explain this - if you can you should believe this answer much more).
'tot'+'e'+'bags'='TOTE BAGS'
'for' is the link.
Can you help me to learn more?
(Another definition for tote bags that I've seen is " spacious containers".)
