Use cheaper packaging on fish in basket (5)
I believe the answer is:
creel
'basket' is the definition.
(basket for holding fish)
'use cheaper packaging on fish' is the wordplay.
I cannot really see how this works, but
'on' could be 're' ('on' can be mean 'with reference to') and 're' is found within the answer.
The remaining letters 'cel' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for creel that I've seen before include "Container for fish" , "Angler's wicker basket" , "lobster basket" , "Fisherman's basket" , "Large fishing basket" .)
