Like the prices in the wine trade (3)
I believe the answer is:
net
'like the prices' is the definition.
I can't judge whether this definition defines the answer.
'in the wine trade' is the wordplay.
'in' says the answer is hidden in the clue.
'NET' is hidden within 'the wine trade'.
Can you help me to learn more?
(Other definitions for net that I've seen before include "Fine open-weave fabric" , "Make" , "Trap; open-weave fabric" , "Overall; mesh" , "land" .)
