I'm a little stuck... Click here to teach me more about this clue!

'money-grubber' is the definition.
(I've seen this before)

I don't understand the remainder of the clue.

(Other definitions for miser that I've seen before include "One giving little" , "Avaricious hoarder" , "Hoarder of money and possessions" , "Skinflint, like Scrooge" , "Someone close" .)

I've seen this clue in the Sydney Morning Herald.
