Bundle (of notes) (3)

I believe the answer is:
wad
'bundle of notes' is the definition.
(wad of banknotes)
This is the entire clue.
(Other definitions for wad that I've seen before include "Small mass of soft material" , "Compact mass" , "Bundle of soft material or of banknotes" , "Pad of loose material used for packing" , "A thick bundle, maybe of money" .)
