Offer too much to get extra shot (7)
I believe the answer is:
overbid
'offer too much' is the definition.
(I've seen this before)
'get extra shot' is the wordplay.
'get' is a charade indicator (letters next to each other).
'extra' becomes 'over' (both can mean left over).
'shot' becomes 'bid' (I can't justify this - if you can you should believe this answer much more).
'over'+'bid' is 'OVERBID'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for overbid that I've seen before include "Make rash offer" , "Contractor's mistake" , "offer too much" , "Higher auction offer" , "offered too much" .)
