A lot of money for parcel (6)
I believe the answer is:
packet
I believe this is a double definition.
'a lot of money' is the first definition.
(I've seen this before)
'parcel' is the second definition.
(packet is a kind of parcel)
'for' is the link.
(Other definitions for packet that I've seen before include "Data transmission unit - large sum" , "Paper or cardboard container" , "Package - large amount - boat" , "A boat; large sum of money" , "Parcel - mail boat" .)
