'economies?' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'make minute' is the wordplay.
'make' becomes 'save' (I can't explain this - if you can you should give a lot more credence to this answer).
'minute' becomes 'time' (time is a kind of minute).
'save'+'time'='SAVE TIME'
