Got excited at one bid (8)
I believe the answer is:
obtained
'got' is the definition.
(obtaining is a kind of getting)
'excited at one bid' is the wordplay.
'excited' indicates an anagram.
'at'+'one'+'bid'='atonebid'
'atonebid' is an anagram of 'OBTAINED'.
(Other definitions for obtained that I've seen before include "Came into possession of" , "Got, procured" , "Into a bed (anag.)" , "Got something" , "Acquired" .)
