Care to shift cocaine in this selling opportunity? (7)
I believe the answer is:
auction
'care to shift cocaine in this selling opportunity?' is the definition.
'auction' can be an answer for 'selling' (auction is a kind of selling). I'm not certain of the rest of the definition.
This is the entire clue.
Can you help me to learn more?
(Other definitions for auction that I've seen before include "Public bidding sale" , "A lot will be seen in this" , "Occasion of lots under the gavel" , "Selling" , "Public sale - type of bridge" .)
