The shopper may take it in hand (3)
I believe the answer is:
bag
'the shopper' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for bag that I've seen before include "Quantity of game shot in a particular period" , "Sack" , "Container for holding or carrying" , "Gladstone, for example" , "Reserve (colloq.)" .)
