Once more makes a profit (5)

I believe the answer is:

again

'once more' is the definition.
(synonyms)

'a profit' is the wordplay.
'profit' becomes 'gain' (synonyms).
'a'+'gain'='AGAIN'

'makes' is the link.

(Other definitions for again that I've seen before include "Predictably perhaps" , "Not for the first time" , "Next time" , "repeat order" , "On the other hand" .)

I've seen this clue in The Irish Independent and The Globe and Mail.
