I'm a little stuck... Click here to teach me more about this clue!

'the highest bidder doesn't' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'leave anything behind' is the wordplay.
I cannot really understand how this works, but
'leave' could be 'take' (taking leave is a kind of leaving) and 'take' is found within the answer.
This explanation may well be incorrect...
